CASTOR 3 Section

CASTOR hit study

  • Run number : 151027
  • Number of Event : 64690 ( using centrality cut )
  • Centrality : 0 ~ 60%
  • Fit function : Landau Function + Gaus Function
  • Fit function range : Landau 0 ~ 150 GeV & Gaus 0~150 GeV

Fit Parameter

  • vector.txt ( mod, sec, par1, par2, par3, par4, par5, par6 )
  • Parameter_1 : Landau Constant value. ( Maximum Value)
  • Parameter_2 : Landau MPV.(Most Probable Value or a location paratmeter)
  • Parameter_3 : Landau Sigma value.
  • Parameter_4 : Gaus Constant value. ( Maximum Value)
  • Parameter_5 : Gaus MPV.(Most Probable Value or a location paratmeter)
  • Parameter_6 : Gaus Sigma value.
  • First row is Landau parameter, Second row is Gaus parameter.

Clustering CASTOR

  • EM part: Mod. 1 + Mod. 2
  • Had1 part : Mod.3 + Mod.4 + Mod.5
  • Had2 part : Mod.10 + Mod.11 + Mod.12 + Mod.13 + Mod.14

Conclusion

  • CASTOR energy distribution was examined for each sectors for every modules (a total of 224 channels)
    • Events with centrality between 0 to 60%

  • CASTOR energy profiles were then fit by “landau” function, and they were calibrated by the width from the fit.
    • A hit is defined as a channel with a CASTOR energy less than the landau width (E < 1 sigma of landau fit)

  • Then we have created dN/dφ distributions and dN/d(φ-Ψ) distribution for each modules
    • Where Event Plane (Ψ) was obtained from silicon tracker

  • CASTOR hits show “out of plane” flow, and it’s strong. But this is problematic.. We expect V2(at η=6) ~ small
    • However this is not only for CASTOR, HF and HE show also “negative” flow for low Et hits.
