    3. etc
      • i made the matching system by myself, instead of matching system in SusyAnalyzer.

  • Changed the cfg file New SusyAnalyzer enable to choose the simulation type, Fast-simulation or Full-simulation. The default type in SusyAnalyzer is Full-simulation. So, when I use the generated event data by fast-simulation, have to change the default.

Mon. 21.

I started to change my code. At first, I did set the array for jet-arrange. The arrange was to be in order of hard-jet(large Pt jet). And next, I did cut the jet number from 6 to 8. Because, this full-hadronic channels have to be more 6-jets.
I discussed Prof. Oh about ttbar process. He taught some physics of ttbar process.

Fri. 18.

* My Work *

There is some information for cross-section in twiki page. ( https://twiki.cern.ch/twiki/bin/view/Main/AlpgenSummer07 ) I chose the luminosity to 1 fb^-1.
event cross-section luminosity event number
tt0jet 334.51 pb 1 fb-1 334510
tt1jet 90.23 pb 1 fb-1 90230
tt2jet 18.75 pb 1 fb-1 18750
tt3jet 3.16 pb 1 fb-1 3160
tt4jet 0.82 pb 1 fb-1 820

* Office 8 R-002 *

I tried to connect the printer. I used USB. There wasn't driver In the installation CD. I found the driver at hp homepage and downloaded that. But there was no action. So, I read the paper for information of printer. I found some comment of enable OS. Enable OS for this printer is Windows XP and MAC. There was no linux.

Maybe, I need ethernet hub and then I try to connect the networking print system.

Thur. 17.

* My Work *

I did some code for jet-parton-matching. And tried to find the document for checking cross-section.

* Office 8 R-002 *

Arrived the new PC and Laserjet printer. there wasn't monitor. I did re-arrange the desks with S.U.Ahn and S.H.Song.

Wed. 16.

I wanted to know the cross-section of each event. But I didn't know where i can get the information. So I asked Dr. chung. There is two way for checking the cross-section. One of that is to find the cfg file for event generating, the other is to find the document for that event. Maybe, I have to use the cfg file in dbs site.

Tues. 15.

Discussed Luc Pape about my result of full-hadronic channel in ttbar. To improve my result, I have to change some method.

  • I have to perform the job by different event number, because the cross-section of each event(tt0jet, tt1jet, tt2jet...) is different.

    Cross-section * luminosity = number of event

    If i choose number of tt0jet event number, the number of tt1jet event is calculated by

    (number of tt0jet event / tt0jet cross-section) * (tt1jet cross-section).

    And number of tt2jet event is calculated by

    (number of tt0jet event / tt0jet cross-section)*(tt2jet cross-section)

    , and so on.

  • I have to use the hemi-analysis for jet pairing.

    I was in trouble of jet pairing these day. But now, I found the good method for that. There is hemi-analysis in susyanalyzer. That consist of two parts. The parts are divided by horizontal line. So, part 1 is upper side and part 2 is down side. This is very good method for pairing. I will use this method.

  • I have to calculate the degree between parton and reconstructed particle by 'dot-product'.

    I used only phi for jet-parton-matching. But I shouldn't ignore the eta. So, I will change the code to dot-product.

Fri. 11.

  • Full hadronic channel :

    Run crab. (CRAB_2_0_4) I couldn't submit job because crab didn't find host of dataset. I don't know what is the matter. The location of dataset is "maite.iihe.ac.be". But, when I created job, there was no host. I used 5 dataset. There are two of dataset in cern. But another dataset are in other site. So, I can't use of such dataset without crab job. So, I did cmsRun by two dataset, being in cern.

  • Single leptonic ttbar events :

    This is event that ttbar decay to 1lepton+4jets+MET. 4jets comes from bbbar and qqbar. I will read the CMSNOTE 2006/024 at first.

Thur. 10.

  • Previously my work :
    • CMSSW version changed. CMSSW_1_5_2 -> CMSSW_1_6_7
    • The jet-parton matching was done.
    • Jet pairing was not good.

  • What to do :
    • Finish full hadronic channel until this week.
    • Start single leptonic ttbar events.

Tues. 8.

CERN vacation was ended and re-opened. i got the e-mail from professor Guinyun Kim. He let me send the report of my work. So, I checked my previous work and result. After that, i sent the e-mail to him.

    This is event that ttbar decay to 1lepton+4jets+MET. 4jets comes from bbbar and qqbar. I will read the CMSNOTE 2006/024 at first.

Thur. 10.

  • Previously my work :
    • CMSSW version changed. CMSSW_1_5_2 -> CMSSW_1_6_7
    • The jet-parton matching was done.
    • Jet pairing was not good.

  • What to do :
    • Finish full hadronic channel until this week.
    • Start single leptonic ttbar events.

Tues. 8.

CERN vacation was ended and re-opened. i got the e-mail from professor Guinyun Kim. He let me send the report of my work. So, I checked my previous work and result. After that, i sent the e-mail to him.

I tried to connect the printer. I used USB. There wasn't driver In the installation CD. I found the driver at hp homepage and downloaded that. But there was no action. So, I read the paper for information of printer. I found some comment of enable OS. Enable OS for this printer is Windows XP and MAC. There was no linux.

Maybe, I need ethernet hub and then I try to connect the networking print system.

  I wanted to know the cross-section of each event. But I didn't know where i can get the information. So I asked Dr. chung. There is two way for checking the cross-section. One of that is to find the cfg file for event generating, the other is to find the document for that event. Maybe, I have to use the cfg file in dbs site.

Tues. 15.

  Discussed Luc Pape about my result of full-hadronic channel in ttbar. To improve my result, I have to change some method.

  • I have to perform the job by different event number, because the cross-section of each event(tt0jet, tt1jet, tt2jet...) is different.

    Cross-section * luminosity = number of event

    If i choose number of tt0jet event number, the number of tt1jet event is calculated by

    (number of tt0jet event / tt0jet cross-section) * (tt1jet cross-section).

    And number of tt2jet event is calculated by

    (number of tt0jet event / tt0jet cross-section)*(tt2jet cross-section)

    , and so on.

  • I have to use the hemi-analysis for jet pairing.

    I was in trouble of jet pairing these day. But now, I found the good method for that. There is hemi-analysis in susyanalyzer. That consist of two parts. The parts are divided by horizontal line. So, part 1 is upper side and part 2 is down side. This is very good method for pairing. I will use this method.

  • I have to calculate the degree between parton and reconstructed particle by 'dot-product'.

    I used only phi for jet-parton-matching. But I shouldn't ignore the eta. So, I will change the code to dot-product.

  • Full hadronic channel :

    Run crab. (CRAB_2_0_4) I couldn't submit job because crab didn't find host of dataset. I don't know what is the matter. The location of dataset is "maite.iihe.ac.be". But, when I created job, there was no host. I used 5 dataset. There are two of dataset in cern. But another dataset are in other site. So, I can't use of such dataset without crab job. So, I did cmsRun by two dataset, being in cern.

Discussed Luc Pape about my result of full-hadronic channel in ttbar. To improve my result, I have to change some method.

  • I have to perform the job by different event number, because the cross-section of each event(tt0jet, tt1jet, tt2jet...) is different.

    Cross-section * luminosity = number of event

    If i choose number of tt0jet event number, the number of tt1jet event is calculated by

    (number of tt0jet event / tt0jet cross-section) * (tt1jet cross-section).

    And number of tt2jet event is calculated by

    (number of tt0jet event / tt0jet cross-section)*(tt2jet cross-section)

    , and so on.

  • I have to use the hemi-analysis for jet pairing.

    I was in trouble of jet pairing these day. But now, I found the good method for that. There is hemi-analysis in susyanalyzer. That consist of two parts. The parts are divided by horizontal line.

  • I have to calculate the degree between parton and reconstructed particle by 'dot-product'.

But, when I created job, there was no host. I used 5 dataset. There are two of dataset in cern. But another dataset are in other site. So, I can't use of such dataset without crab job. So, I did cmsRun by two dataset, being in cern.

  • Single leptonic ttbar events :

    This is event that ttbar decay to 1lepton+4jets+MET. 4jets comes from bbbar and qqbar. I will read the CMSNOTE 2006/024 at first.

* Meeting *

  • DAQ group meeting ( Am 11:00 ) with S.K.Oh, G.N.Kim, J.H.Chung, G.S.Kim, S.U.Ahn, S.H.Song, J.W.Seo.
    1. Have to meet and discuss month by month.
    2. Send the report about work to professor monthly.
    3. When I am faced with difficulties, doing something or some physics..., ask Dr. Ro and Dr. chung or... someone.

  • Changed the cfg file New SusyAnalyzer enable to choose the simulation type, Fast-simulation or Full-simulation. The default type in SusyAnalyzer is Full-simulation. So, when I use the generated event data by fast-simulation, have to change the default.
 
Mon. 21.
I started to change my code. At first, I did set the array for jet-arrange. The arrange was to be in order of hard-jet(large Pt jet). And next, I did cut the jet number from 6 to 8. Because, this full-hadronic channels have to be more 6-jets.
I discussed Prof. Oh about ttbar process. He taught some physics of ttbar process.

Fri. 18.
* My Work *

There is some information for cross-section in twiki page. ( https://twiki.cern.ch/twiki/bin/view/Main/AlpgenSummer07 ) I chose the luminosity to 1 fb^-1.
event cross-section luminosity event number
tt0jet 334.51 pb 1 fb-1 334510
tt1jet 90.23 pb 1 fb-1 90230

tt3jet 3.16 pb 1 fb-1 3160
tt4jet 0.82 pb 1 fb-1 820

* Office 8 R-002 *

I tried to connect the printer. I used USB. There wasn't driver In the installation CD. I found the driver at hp homepage and downloaded that. But there was no action. So, I read the paper for information of printer. I found some comment of enable OS. Enable OS for this printer is Windows XP and MAC. There was no linux.

Maybe, I need ethernet hub and then I try to connect the networking print system.

Thur. 17.
* My Work *

I did some code for jet-parton-matching. And tried to find the document for checking cross-section.

* Office 8 R-002 *

Arrived the new PC and Laserjet printer. there wasn't monitor. I did re-arrange the desks with S.U.Ahn and S.H.Song.

Wed. 16.
I wanted to know the cross-section of each event. But I didn't know where i can get the information. So I asked Dr. chung. There is two way for checking the cross-section. One of that is to find the cfg file for event generating, the other is to find the document for that event. Maybe, I have to use the cfg file in dbs site.

Tues. 15.
Discussed Luc Pape about my result of full-hadronic channel in ttbar. To improve my result, I have to change some method.

  • I have to perform the job by different event number, because the cross-section of each event(tt0jet, tt1jet, tt2jet...) is different.

    Cross-section * luminosity = number of event

    If i choose number of tt0jet event number, the number of tt1jet event is calculated by

    (number of tt0jet event / tt0jet cross-section) * (tt1jet cross-section).

    And number of tt2jet event is calculated by

    (number of tt0jet event / tt0jet cross-section)*(tt2jet cross-section)

    , and so on.

  • I have to use the hemi-analysis for jet pairing.

    I was in trouble of jet pairing these day. But now, I found the good method for that. There is hemi-analysis in susyanalyzer. That consist of two parts. The parts are divided by horizontal line. So, part 1 is upper side and part 2 is down side. This is very good method for pairing. I will use this method.

  • I have to calculate the degree between parton and reconstructed particle by 'dot-product'.

    I used only phi for jet-parton-matching. But I shouldn't ignore the eta. So, I will change the code to dot-product.

Fri. 11.
  • Full hadronic channel :

    Run crab. (CRAB_2_0_4) I couldn't submit job because crab didn't find host of dataset. I don't know what is the matter. The location of dataset is "maite.iihe.ac.be". But, when I created job, there was no host. I used 5 dataset. There are two of dataset in cern. But another dataset are in other site. So, I can't use of such dataset without crab job. So, I did cmsRun by two dataset, being in cern.

  • Single leptonic ttbar events :

    This is event that ttbar decay to 1lepton+4jets+MET. 4jets comes from bbbar and qqbar. I will read the CMSNOTE 2006/024 at first.

Thur. 10.
  • Previously my work :
    • CMSSW version changed. CMSSW_1_5_2 -> CMSSW_1_6_7

  • Full hadronic channel :

    Run crab. (CRAB_2_0_4) I couldn't submit job because crab didn't find host of dataset. I don't know what is the matter. The location of dataset is "maite.iihe.ac.be". But, when I created job, there was no host. I used 5 dataset. There are two of dataset in cern. But another dataset are in other site. So, I can't use of such dataset without crab job. So, I did cmsRun by two dataset, being in cern.

  • Single leptonic ttbar events :

Changed:
<
<		 This is event that ttbar decay to 1lepton+4jets+MET. 4jets comes from bbbar and qqbar. I will read the CMSNOTE 2006/066 at first.

  • Previously my work :
    • CMSSW version changed. CMSSW_1_5_2 -> CMSSW_1_6_7
    • The jet-parton matching was done.
    • Jet pairing was not good.

  • What to do :
    • Finish full hadronic channel until this week.
    • Start single leptonic ttbar events.
