Higgs 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 کاملEvidence for the 125 GeV Higgs Boson Decaying into Taus at the CMS Experiment
A search for a standard model (SM) Higgs boson decaying into a pair of τ 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 fb−1 at a centre-of-mass energy of 7 TeV and 19.7 fb−1 at 8 TeV. Each τ lepton decays hadronically or leptonically to an electron or a muon, leading to six different final...
متن کاملMass-degenerate Higgs bosons at 125 GeV in the two-Higgs-doublet model
The analysis of the Higgs boson data by the ATLAS and CMS Collaborations appears to exhibit an excess of h ! events above the Standard Model (SM) expectations, whereas no significant excess is observed in h ! ZZ ! four lepton events, albeit with large statistical uncertainty due to the small data sample. These results (assuming they persist with further data) could be explained by a pair of nea...
متن کامل[in2p3-00705410, v1] SUSY and a 125 GeV Scalar
An excess of events at a mass of ∼ 125 GeV has been reported by both ATLAS and CMS collaborations using 5 fb−1 of data. If this excess of events is confirmed by further searches with more data, it will have extremely important consequences in the context of supersymmetric extensions of the Standard Model. We show that for a Standard Model like Higgs boson with a mass 122.5 < Mh < 127.5 GeV, sev...
متن کاملBeyond the standard Higgs after the 125 GeV Higgs discovery.
An elementary weakly coupled and solitary Higgs boson allows one to extend the validity of the Standard Model up to very high energy, maybe as high as the Planck scale. Nonetheless, this scenario fails to fill the universe with dark matter and does not explain the matter-antimatter asymmetry. However, amending the Standard Model tends to destabilize the weak scale by large quantum corrections t...
