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
