2.8 TeV and 4 TeV Hydjet sample comparision

Introduction

Purpose of this study is to find out different characteristics of muon, J/psi and Upilon in the 4 TeV and 2.76 TeV Hydjet samples.

Data samples are located under MIT T2 servers. In the DBS, dataset name is :

  • 2.76 TeV (~ 1M events) : /Hydjet_Quenched_MinBias_2760GeV_MC_3XY_V24_GEN-SIM-RAW/davidlw-Hydjet_Quenched_MinBias_2760GeV_MC_3XY_V24_GEN-SIM-RAW-51550601a6965131c06787129d40c7a9/USER
  • 4 TeV (~ 35000 events) : /Hydjet_MinBias_4TeV/Summer09-MC_31X_V9-v1/GEN-SIM-RAW

Used program is :

Mother particle comparsion

  • Comparision :
    • 2.8 TeV has less mother species.
    • Transverse momentum (pt) trends are similar between 2.76 TeV and 4 TeV for same mom ID
