Data 2011 2011 A search for neutral Higgs bosons in proton-proton collisions at the LHC at a center-of-mass energy of 7 TeV is presented. The results are based on a data sample corresponding to an integrated luminosity of 1.6/fb recorded by the CMS experiment. The search uses decays of the Higgs bosons to tau pairs, including the cases where the Higgs boson is produced in association with a b-quark jet (MSSM search) or two forward jets from vector boson fusion Higgs boson production (SM search). No excess is observed in the tau-pair invariant-mass spectrum. The resulting upper limits on the Higgs boson production cross section times branching fraction to tau pairs, as a function of the pseudoscalar Higgs boson mass, yield stringent new bounds in the MSSM parameter space. Data 2011 2011 The overall combination is presented of eight standard model (SM) Higgs boson searches performed by the CMS Collaboration using the following Higgs boson decay signatures: $H \to \gamma\gamma$, $H \to \tau\tau$, $H \to bb$, $H \to WW \to 2\ell 2\nu$, $H \to ZZ \to 4\ell$, $H \to ZZ \to 2\ell 2 \tau$, $H \to ZZ \to 2\ell 2\nu$, and $H \to ZZ \to 2\ell 2q$. Depending on the analysis, the amount of data used corresponds to 1.1-1.7~fb$^{-1}$ of integrated luminosity. The SM Higgs boson is excluded at 95\% C.L. in three mass ranges 145-216, 226-288, and 310-400~GeV/$c^2$. The expected exclusion in the absence of a signal is 130-440~GeV/$c^2$. The largest excursion of the observed data from the expected has a probability of 0.4 after taking into account the look-elsewhere effect. At 90\% C.L., we exclude the SM Higgs boson in the continuous mass range from 144-440~GeV/$c^2$. The reported limits were obtained using the modified frequentist construction known as the $\mathrm{CL_s}$ method. Data 2011 2011 This note describes the search for a Higgs boson decaying into diphotons in pp collisions at the LHC at a center-of-mass energy of 7~TeV. Data-driven methods are used to evaluate the reconstruction and selection performance for the signal, and the background is evaluated from a fit to the data. The analysis is performed on a dataset corresponding to 1.66~fb$^{-1}$ of data recorded in 2011 by the CMS experiment. Limits are set on the cross section of a Standard Model Higgs boson decaying to 2 photons, and on the cross section of a fermiophobic Higgs boson decaying to 2 photons. The expected exclusion limit at 95\% CL is between 2.7 and 4.7 times the Standard Model cross section, and the observed limit fluctuates between about 1.3 and 8 times the Standard Model cross section. For the fermiophobic model, the expected exclusion limit at 95\% CL covers the mass range between 110-116.5~GeV$/c^{2}$, while the data excludes only the mass range 110-112~GeV$/c^{2}$. Data 2011 2011 A search for the standard model Higgs boson is performed in a data sample corresponding to an integrated luminosity of $1.1$~fb$^{-1}$, recorded by the CMS detector in proton-proton collisions at the LHC with a 7~TeV center-of-mass energy. The following modes are studied: $W(\mu\nu)H,~ W(e\nu)H,~ Z(\mu\mu)H,~ Z(ee)H$ and $Z(\nu\nu)H$, with the Higgs decaying to $b\bar{b}$ pairs. 95\% C.L. upper limits on the VH production cross section are derived for a Higgs mass between 110 and 135 GeV. The expected (observed) upper limit at 115~GeV is found to be 5.7 (8.3) times the standard model expectation. Data 2011 2011 The overall combination is presented of six standard model (SM) Higgs boson searches performed by the CMS Collaboration using the following Higgs boson decay signatures: $H \to \gamma\gamma$, $H \to \tau\tau$, $H \to WW \to 2\ell 2\nu$, $H \to ZZ \to 4\ell$, $H \to ZZ \to 2\ell 2\nu$, and $H \to ZZ \to 2\ell 2q$. Depending on the analysis, the amount of data used corresponds to 1.0-1.1~fb$^{-1}$ of integrated luminosity. The conclusion of this combination is that the SM Higgs boson is excluded at 95\% C.L. in two mass ranges 149-206 and 300-440~GeV/$c^2$, as well as several narrower intervals in between. The expected exclusion in the absence of a signal is 127-420~GeV/$c^2$. At 90\% C.L., we exclude the SM Higgs boson in the mass range from 145-480~GeV/$c^2$. The same experimental search results, reinterpreted in the context of the standard model with 4 fermion generations (SM4), allow us to exclude the SM4 Higgs boson with a mass in the range 120-600 GeV/$c^2$ at 95\% C.L. Data 2011 2011 This note describes the search for a Higgs boson decaying into diphotons in the CMS detector. Data-driven methods are used to evaluate the reconstruction and selection performance for the signal, and the background is evaluated from a fit to the data. The analysis is performed on a dataset corresponding to $1.09~\fbinv$ of data collected in 2011. Limits are set on the cross section of a Standard Model Higgs boson decaying to 2 photons, and on the cross section of a fermiophobic Higgs boson decaying to 2 photons. The expected exclusion limit at 95\% CL is less than 4 times the Standard Model cross section between 110 and 135~\GeVcc, and the actual excluded ratio to the SM cross section varies between 1.9 and 7.4. For a fermiophobic model the expected exclusion limit at 95\% CL is less than the cross section predicted by the model between 110 and 114~\GeVcc.

Data 2011 2011 The results of a search for neutral MSSM Higgs boson production in $pp$ collisions at the LHC at a center-of-mass energy of 7~TeV are presented, based on a data sample corresponding to an integrated luminosity of 36 pb$^{-1}$. We search for decays of the Higgs bosons to tau lepton pairs, using the final states with one identified $e$ or $\mu$ from leptonic tau decay plus a reconstructed hadronic decay of a tau lepton, and also the final state with two leptonic tau decays, and then fully reconstruct the original tau lepton pair kinematics using a novel likelihood algorithm. No excess is observed in the fully reconstructed tau pair invariant mass spectrum. The resulting upper bounds on the Higgs production cross section times branching ratio to tau pairs as a function of the Higgs boson mass yield stringent new bounds in the MSSM parameter space $m_A$ versus $\tan\beta$, extending as low as $\tan\beta = 23$ for $m_A=130$ GeV/$c^2$. Smith, Wesley H 10.5170/CERN-2004-010.34 2004 2004 Green, D 2005 2005 There exist substantial backgrounds to the vector boson fusion production of Higgs at the LHC. Mass variables are studied which may alleviate the need to assume a spin zero WW resonance in order to achieve a sufficient signal to noise ratio in the two jet plus two lepton and missing energy final state.
