UED effects on Higgs signals at LHC
نویسنده
چکیده
A major focus at the Large Hadron Collider (LHC) will be Higgs boson studies and it would be an interesting prospect to simultaneously probe for physics beyond the Standard Model (SM) in the Higgs signals. In this work we show as to what extent, the effects of Universal Extra Dimension (UED) can be isolated at the LHC through the Higgs signals. By doing a detailed study of the different uncertainties involved in the measurement of the rates for the process pp → h → γγ we estimate the extent to which these uncertainties can mask the effects of the contributions coming from UED.

متن کاملقیدهای تک Z روی مدل ماده تاریک فرمیونی با واسطه شبه اسکالر در LHC
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 کاملIdentifying the contributions of Universal Extra Dimensions in the Higgs sector at linear e + e − colliders
We study the dilepton-dijet signal in the dominant Higgs production channel at a linear e+e− collider. We estimate the effects of Universal Extra Dimension (UED) by a simple analysis of the cross-sections. The heavy Kaluza-Klein excitations of the Standard Model fields in UED can significantly alter the decay properties of the Higgs boson to loop-driven final states. We show that by taking a si...
متن کاملHiggs bosons at 98 and 125 GeV at LEP and the LHC
We discuss NMSSM scenarios in which the lightest Higgs boson h1 is consistent with the small LEP excess at ∼ 98 GeV in e+e− → Zh with h→ bb and the heavier Higgs boson h2 has the primary features of the LHC Higgs-like signals at 125 GeV, including an enhanced γγ rate. Verification or falsification of the 98 GeV h1 may be possible at the LHC during the 14 TeV run. The detection of the other NMSS...
متن کاملTop Squark Effects on Higgs Boson Production and Decays at the LHC
In the Minimal Supersymmetric Standard Model, one of the scalar top quarks can be relatively light and its couplings to Higgs bosons strongly enhanced. I will discuss two consequences of this feature: 1) the effects of scalar top loops on the main production mechanism of the lightest Higgs boson at the LHC, the gluon–fusion mechanism gg → h, and on the important decay channel into two photons h...
