potential at the LHC : channels relevant for SM Higgs
نویسندگان
چکیده
The discovery potential of Standard Model Higgs searches at the LHC at 14 TeV center-of-mass energy is reviewed. Decay channels such as H → γγ, H → ZZ → 4l, H → WW ⋆ and H → ττ are considered. Results are based on the most recent full GEANT-based simulations performed by the ATLAS and CMS experiments.

In this research we study the Mono-Z signature along with dark matter production at the LHC in a renormalizable dark matter model. We look at processes with L+L-+MET in the final state. We simulate signal and background events at central mass energy 14 TeV We then evaluate the LHC sensitivities for some points in the model parameter space for two integrated luminosities L=100 fb-1 and L=1 ab-1 ...
متن کاملMeasuring Trilinear Higgs Coupling in WHH and ZHH Productions at the HL-LHC
Determination of trilinear Higgs coupling (λHHH = κλ SM HHH) through Higgs pair productions is a major motivation for the LHC high luminosity phase. We perform a detailed collider simulation to explore the potential of measuring λHHH in the V HH (V = W,Z) production at the HL-LHC. We find that the trilinear Higgs coupling in the SM (λ HHH) could be measured at the level of 1.3σ. Combining with ...
متن کاملDiscovery Potential for the SM Higgs Boson in the Inclusive Search Channels
This paper gives an overview of the potential to discover a Standard Model Higgs Boson in the inclusive search channels at the ATLAS and CMS experiments at the LHC. The most important decay modes, H → γγ, H → WW → llνν and H → ZZ → 4l are described and a summary of recently published analyses using realistic detector simulations is presented.

متن کاملProduction of Neutral Higgs + Jet at the Lhc in the Sm and the Mssm∗
The production of SM Higgs bosons in hadron collisions at the LHC will proceed mainly via gluon fusion (gg → H). The detection of a SM Higgs boson with a mass below 140GeV at the LHC is rather difficult because the predominant decay into a bb̄-pair is swamped by the large QCD two-jet background . Therefore, only through observation of the rare decay into two photons, is the inclusive single Higg...
متن کاملHiggs boson self-couplings at the LHC as a probe of extended Higgs sectors
A study of two-Higgs-doublet models (2HDM) in the decoupling limit reveals the existence of parameter configurations with a large triple-Higgs self-coupling as the only low-energy trace of the departure from a Standard Model (SM) Higgs sector. This observation encourages attempts to search for double Higgs production at the Large Hadron Collider (LHC) even in mass regions which have been shown ...
