Measurement of Psi(2S) to Psi(1S) ratio in p+Pb Collisions

Goal: To measuren ration of Psi(2S) and J/Psi in pPb collisions

Data Used: (Based On CMS-AN-13-346)

  • Mis-aligned 1st 7 runs (210498-): store/caf/user/lamia/merged_pPbData_1st_ntuple_ReprocessedReco-v1_GR_P_V43F_pileupRej_muID_tot.root
  • 1st run Pbp (run 210-) : store/caf/user/lamia/merged_pPbData_1st_ntuple_PromptReco-v1_GR_P_V43D_pileupRej_muID_tot.root
  • 2nd run pPb (run21131-) : /store/caf/user/lamia/merged_pPbData_2nd_ntuple_PromptReco-v1_GR_P_V43D_pileupRej_muID_tot.root

Signal Extraction: (Based On CMS-AN-12-118)

  • Unbinned maximum likely hood fitting using rooFit
  • Signal Shape :CB + Gaussian for both Psi(1S) and Psi(2S)
  • Background : Chebechev Polynomial
