Title: Looking for a light Higgs boson in the Zγ→ll̄γ channel

Abstract

The final state obtained when a Higgs boson decays to a photon and a Z boson has been mostly overlooked in current searches for a light Higgs boson. However, when the Z boson decays leptonically, all final state particles in this channel can be measured, allowing for accurate reconstructions of the Higgs mass and angular correlations. We determine the sensitivity of the Large Hadron Collider (LHC) running at center of mass energies of 8 and 14 TeV to Standard Model (SM) Higgs bosons with masses in the 120–130 GeV range. For the 8 TeV LHC, sensitivity to several times the SM cross section times branching ratio may be obtained with 20 inverse femtobarns of integrated luminosity, while for the 14 TeV LHC, the SM rate is probed with about 100 inverse femtobarns of integrated luminosity.

Search for a Higgs boson in the decay channel $$H$$ to ZZ(*) to $$q$$ qbar $$\ell^-$$ l+ in $pp$ collisions at $$\sqrt{s}=7$$ TeV

Journal Article Chatrchyan, Serguei ; et al. - Journal of High Energy Physics (Online)

A search for the standard model Higgs boson decaying into two Z bosons with subsequent decay into a final state containing two quark jets and two leptons, H to ZZ(*) to q q-bar l-l+ is presented. Results are based on data corresponding to an integrated luminosity of 4.6 inverse femtobarns of proton-proton collisions at sqrt(s)=7 TeV, collected with the CMS detector at the LHC. In order to discriminate between signal and background events, kinematic and topological quantities, including the angular spin correlations of the decay products, are employed. Events are further classified according to the probability of the jets tomore »« less

Search for invisible decays of Higgs bosons in the vector boson fusion and associated ZH production modes

Journal Article Chatrchyan, Serguei - European Physical Journal. C, Particles and Fields

A search for invisible decays of Higgs bosons is performed using the vector boson fusion and associated ZH production modes. In the ZH mode, the Z boson is required to decay to a pair of charged leptons or a b b-bar quark pair. The searches use the 8 TeV pp collision dataset collected by the CMS detector at the LHC, corresponding to an integrated luminosity of up to 19.7 inverse femtobarns. Certain channels include data from 7 TeV collisions corresponding to an integrated luminosity of 4.9 inverse femtobarns. The searches are sensitive to non-standard-model invisible decays of the recently observedmore »« less

Evidence for the 125 GeV Higgs boson decaying to a pair of $$\tau$$ leptons

Journal Article Chatrchyan, Serguei - Journal of High Energy Physics (Online)

A search for a standard model Higgs boson decaying into a pair of tau leptons is performed using events recorded by the CMS experiment at the LHC in 2011 and 2012. The dataset corresponds to an integrated luminosity of 4.9 inverse femtobarns at a centre-of-mass energy of 7 TeV and 19.7 inverse femtobarns at 8 TeV. Each tau lepton decays hadronically or leptonically to an electron or a muon, leading to six different final states for the tau-lepton pair, all considered in this analysis. An excess of events is observed over the expected background contributions, with a local significance largermore »« less

Search for the standard model Higgs boson produced in association with a standard W or a Z boson and decaying to bottom quarks

Journal Article Chatrchyan, Serguei ; et al., - Physical Review D

A search for the standard model Higgs boson (H) decaying to b b-bar when produced in association with a weak vector boson (V) is reported for the following channels: W(mu nu)H, W(e nu)H, W(tau nu)H, Z(mu mu)H, Z(e e)H, and Z(nu nu)H. The search is performed in data samples corresponding to integrated luminosities of up to 5.1 inverse femtobarns at sqrt(s) = 7 TeV and up to 18.9 inverse femtobarns at sqrt(s) = 8 TeV, recorded by the CMS experiment at the LHC.

The Higgs boson in the Standard Model theoretical constraints and a direct search in the wh channel at the Tevatron

Thesis/Dissertation Huske, Nils Kristian

We have presented results in two different yet strongly linked aspects of Higgs boson physics. We have learned about the importance of the Higgs boson for the fate of the Standard Model, being either only a theory limited to explaining phenomena at the electroweak scale or, if the Higgs boson lies within a mass range of 130 < m_H < 160 GeV the SM would remain a self consistent theory up to highest energy scales O(m_Pl). This could have direct implications on theories of cosmological inflation using the Higgs boson as the particle giving rise to inflation in the verymore »« less
