2010.01.26 Endcap/Barrel clustering with official W-MC

Simulations: official pp 500GeV pythia W production

Two channels being analyzed:

  • W+ -> e+ nu (rcf10010*.root)
  • W-  -> e- nu (rcf10011*.root)

Lepton from W in the Endcap: 1.2 < eta_lepton < 1.9

Figure 1: Lepton yield vs. energy

Figure 2: Lepton (left) E1x1/E_thrown and (right) E2x2/E_thrown energy ratio
Skewed gaussian fits: [const]*exp(-0.5*((x-[mean])/([sigma]*(1+[skewness]*(x-[mean]))))**2)

Figure 3: Endcap EMC lepton E3x3/E_thrown energy ratio

Figure 4: Endcap 2x2 sampling fraction (s.f.) vs. thrown lepton (left) energy and (right) eta
S.f. is defined as an average E_2x2/E_thrown for E_2x2/E_thrown>0.8

Figure 5: Endcap 3x3 sampling fraction (s.f.) vs. thrown lepton (left) energy and (right) eta
S.f. is defined as an average E_3x3/E_thrown for E_3x3/E_thrown>0.8


Lepton from W in the Barrel: |eta_lepton| <1

Figure 6: Lepton yield vs. energy

Figure 7: Lepton (left) E1x1/E_thrown and (right) E2x2/E_thrown energy ratio

Figure 8: Barrel EMC lepton E3x3/E_thrown energy ratio

Figure 9: Barrel 2x2 s.f. vs. thrown lepton (left) energy and (right) eta
S.f. is defined as an average E_2x2/E_thrown for E_2x2/E_thrown>0.8

Figure 10: Barrel 3x3 s.f. vs. thrown lepton (left) energy and (right) eta
S.f. is defined as an average E_3x3/E_thrown for E_3x3/E_thrown>0.8
