Pre-Data

Date Analysis Main Results Documentation
27 Oct 2010 Monte Carlo: Projected SM Higgs sensitivities for sqrt(s)=7 and 8 TeV with L=1-10 fb-1 Projections are obtained using an expanded list of SM Higgs signatures, namely: H→WW→2l2v (+0/1 jets), VBF H→WW→2l2v, H→ZZ→4l, H→ZZ→2l2ν, H→ZZ→2l2b, H→γγ, VBF H→ττ, associate production VH→V(bb) (highly boosted), associate production ZH→Z(WW)→(ll)(lvjj), associate production WH→W(WW)→(lv)(lvjj) (same sign di-leptons). At sqrt(s)=7 TeV with L=5 fb-1, CMS is expected to reach an exclusion sensitivity in the mass range from the LEP limits (114 GeV) to 600 GeV. At sqrt(s)=8 TeV with L=5 fb-1, the observation sensitivity in the same mass range of 114-600 GeV is expected to be 3σ or higher, depending on the Higgs mass. The plots and a brief summary can be found here. They will be soon included in NOTE-2010/008.
6 Apr 2010 Monte Carlo: Projected sensitivities for sqrt(s)=7 TeV and L=1 fb-1 Projections are presented for three SM Higgs signatures, H→WW→2l2v, H→ZZ→4l, H→γγ, their combination, and the MSSM Higgs channel pp→bbΦ→bb(ττ). SM Higgs searches are expected to reach a discovery level sensitivity for mH=160-170 GeV and an exclusion level sensitivity for mH=145-190 GeV. Higgs boson mass mH<400 GeV can be excluded in models with four generations of quarks, regardless of how heavy their masses might be. Fermiophobic Higgs can be excluded for mH<110 GeV. The expected discovery/exclusion sensitivities for the neutral MSSM Higgs bosons are given as contours in the (mA,tanβ)-plane. At low mA~90 GeV, the discovery can be possible for tanβ>20 and the exclusion limit is expected to reach down to tanβ~15. NOTE-2010/008. The plots and a brief summary can be found here
Feb 2009 Monte Carlo: Combination of H→WW and H→ZZ analyses. Impact of the LHC COM energy change from 14 to 10 TeV Running at 10 TeV requires about 2 times larger integrated luminosity to reach the same sensitivity for SM Higgs. At 10 TeV, an exclusion of the SM Higgs boson with mH~160-170 GeV would require ~200 pb-1 Details can be found here
Jan 2009 Monte Carlo: H→ZZ→4l analysis at 14 TeV and 1 fb-1 At 14 TeV and 1 fb-1, discovery of the SM Higgs boson is out of reach. A 95%CL exclusion is possible in the mass range of about 190-230 GeV PAS HIG-08/003
Jan 2009 Monte Carlo: H→WW→2l2v at 14 TeV and 1 fb-1 At 14 TeV and 1 fb-1, discovery is possible for the SM Higgs boson with mH~160-170 GeV. A 95%CL exclusion is possible in the mass range 140-200 GeV PAS HIG-08/006
2008 Monte Carlo: pp→qqH, H→τhad τl at 14 TeV and 1 fb-1 At 14 TeV and 1 fb-1, neither discovery nor 95%CL exclusion of the SM Higgs boson are possible. Exclusion is possible on anomalous x-section σ/σSM~10 in mass range 115-135 GeV. Data driven techniques for controlling main background components are presented. PAS HIG-08/008 and HIG-08/001
2006-2007 Monte Carlo: CMS Physics Potential at 14 TeV and integrated luminosity up to 30 fb-1 Large collection of physics potential studies for Standard Model, Higgs, SUSY, and beyond. CMS Physics TDR, vol. II. CMS NOTES related to the Higgs studies presented in the PTDR (and a few analyses approved right after PTDR) can be found here
