1. psi(2S) Measument with CMS 10 TeV Data
Purpose: to measure psi(2S) cross section and pt
distribution with early 10 TeV CMS data
Signal: pp→g psi(2S) →g J/psi pi+pi-
Generator: Pythia to produce
pp→g psi(2S), here
psi(2S)→J/psi pi+pi-, J/psi pi0pi0, J/psi eta, J/psi pi0 ,
chi0,1,2 gamma,
J/psi→mu+mu-,
pp→cc~g(or q), cc~ →psi(2S)g
CMSSW_2_1_9

2. psi(2S) Measument with CMS 10 TeV Data
Cross Section: 6.329E-03mb
Produced Events: 50000
Preselection: dimu |eta|<2.5 and pt>2.5,
1000 events remains

3. psi(2S) Measument with CMS 10 TeV Data
Muon is global Muon

4. psi(2S) Measument with CMS 10 TeV Data
J/psi is consist of 2 muons

5. psi(2S) Measument with CMS 10 TeV Data
Psi(2S) is consist of J/psi pi+pi-
Cut 1: number of dimuons >= to get fig9, fig 10 is a part of fig 9
Cut 2: △R(Psi(2S),pi)<1.5 to get fig11, Cut 3: 2pi mass<0.59 to get fig12,

6. psi(2S) Measument with CMS 10 TeV Data
Psi(2S) is consist of J/psi pi+pi-(con’t)
Cut 4: chisquid squared < to get fig14 fig 10
