Boosted W /Z Experimental Results
Dumping ground for 'results'...
Leptonic Boosted Z Efficiency
James
Toy MC result for Z to ee (tuned to fit CMS fullsim):
Leptonic Boosted W Reconstruction
James
Define neutrino momentum 3-vector as:
Reconstructed W mass from 1 TeV u* (PGS):
Signal reconstructed P_t (LHC full-sim):
Good discriminant is to plot against angular separation in phi between MET and lepton (PGS is on the left, LHC full-sim on the right):
Various backgrounds:
Efficiency Measurements
Define cut as dPhi(MET, Ele) < (Pt(Pair) / 80)
Channel: Cut efficiency (Total event efficiency)
1 TeV u*: 0.94 (0.77)
TT+Jets: 0.52 (0.08)
Z+Jets: 0.50 (0.50)
W+Jets: 0.50 (0.50)
Hadronic W/Z Reconstruction
Heather and Muge
