1. CMS-Bijing weekly meeting
H->γγ October Exercise

IHEP-Beijing
CMS-Bijing weekly meeting
Oct. 30, 2009
Two simple exercises for the H->γγ:
HiggsGamGamValid
HiggsGamGamVtx
3 groups involved in the HiggsGamGamValid

Beijing/IPNL: Junquan Tao, Hong Xiao, Anna Falkiewicz, Susan Gascon-Shotkin

2. The HggOctEx Code
A standard CMSSW Analyzer Codes in 3_1_X were developed and checked into the CVS package by J. Tao:
src: HggOctEx.cc interface: HggOctEx.h
test: hggoctex_cfg.py, MultiStack.C and all the plots of my results
Modifications (S. Gascon, A. Falkiewicz, J. Tao and H. Xiao, thanks to V. Litvin and others for disccusion):
1: HLT 'All-pass' (HLT selection done upstream, for now)
2: ISO variables plotted directly *after* selection of leading and
subleading (in pt) photons, ISO cuts imposed *before* all plots
(formerly was *after* all plots except m_2gamma). Can steer intermediate
parts of selection with configuration
3: Added eta limits on photons: Incorporated into choice of leading
and subleading photons are chosen
4: Cleanup/uniformisation of histo binning, limits, titles…
5: Two Separate new versions committed and tagged, one with solid,
one with hollow cone track isolation (SolidConeTrackIso03_3_1_X ,
Hollow ConeTrackIso03_3_1_X)
6: Isolation bias: selected iaolated 2 highest PT photons
Currently just gives histograms (can add output root tree later)
Runing with Crab by J. Tao, H. Xiao and A. Falkiewicz many times with all the SD samples of HiggsGaGa.

3. Datasets after skimming of HiggsGaGa
Secondary dataset: SD_Photon20 samples for 10TeV and 7TeV
Secondary dataset: SD_DoublePhoton10 samples for 10TeV and 7TeV (not actually needed for the plots for october exercise, but only for tests)
8 sets of plots: AfterSkim and AfterCuts for both 7 and 10 TeV with SD_Photon20 and SD_DoublePhoton10 tt

4. Basic variables and events selections
Basic variables for plots:
for events passing the skim:
Photon variables for leading and subleading photon separately: Et, eta, sigma_ietaieta, H/E, R9, Isol_tk, Isol_ECAL, Isol_HCAL (define variables, same as for selection below)
Diphoton variables: M_gamgam, Pt_gamgam, costhetastar, eta_gamgam, Pz_gamgam
Primaryvertex_with_tracks (for now choose the one with maximal Sum(pt) )
Z, Sum(|pt|), |Sum(pt)|, Ntk
For events with at least one photon with 2 converted tracks, with valid conversionVertex and with |deltaCot(theta)|<0.15:
Zvtx_fromconv; Zvtx_fromconv-Z_fromtracks
Additional plots for Fermiophobic Higgs:
Uncorrected calo jets: Leading and subleading et, eta, Deta, M_jj
MET: caloMET, tcMET
for events passing the selections: Same plots as above
Selections:
Pt leading > 30 GeV && Pt sub-leading > 20 GeV && |eta| both photons <2.5
Isolation (leading and subleading the same):
Tracker (Sum Pt tracks solid cone Dr<0.3 less than ~2 GeV)
ECAL (Jurassic sum Et solid cone Dr<0.3 less than ~8 GeV)
HCAL (Jurassic sum Et solid cone Dr<0.3 less than ~8 GeV)

17. Summary
Hgg Oct exercise for HiggsGamGamValid have been
From the results, there’s no big problem about the analysis codes and the SD data samples
Comparing with others, the results are almost the same.
