ISR/FSR studies
Last update 23 December 2005
Pythia Drell-Yan from 1 TeV
PDF=CTEQ5L (HUGE statistics sample);
pT(e+/-)>20 GeV, eta(e+/-)<2.5
Cross sections before cuts = 6.6 fb (ISR/FSR off), 6.6 fb (ISR/FSR on)
Cross sections after cuts = 5.71 fb (ISR/FSR off), 5.74 fb (ISR/FSR on)
Comparison of kinematic observables
(dilepton invariant mass, FB asymetry, Z' rapidity,
Z' pT, lepton pT and lepton pseudo rapidity)
with and w/o ISR/FSR (left)
and ratio between both (right); relative normalisation by number of events after cuts :
