We study the implications of the LHC Higgs signals on the Higgs mixing in the next-to-minimal supersymmetric standard model (NMSSM). The Higgs couplings can depart from their values in the standard model (SM) due to mixing effects. However…

We have done a fast simulation analysis of the charged Higgs signal at LHC in the 1 and 3 prong hadronic $\tau$-jet channels along with the $t \bar t$ background. The $\tau$ polarization was effectively used to suppress the background in…

Signal-background interference effects are studied for H --> WW and H --> ZZ searches in gluon fusion at the LHC. More specifically, the interference in the channels with semileptonic weak boson pair decay is analysed for light and heavy…

The existence of charged Higgs boson(s) is inevitable in models with two (or more) Higgs doublets. Hence, their discovery would constitute unambiguous evidence for new physics beyond the Standard Model (SM). Taking into account all relevant…

In extended Higgs models, the Higgs boson may decay into a pair of light CP-odd scalars, with distinctive collider signatures. We study the ensuing Higgs signals at the upgraded Tevatron, considering the subsequent decays of the scalars…

We present the combination of searches for the Standard Model Higgs boson, using up to 10 \invfb\ of $p\bar p$ collisions at $\sqrts$=1.96 TeV collected with the CDF and \dzero\ detectors at the Fermilab Tevatron collider. The major…

Charged Higgs bosons are predicted in variety of theoretically well-motivated new physics models with extended Higgs sectors. In this study, we focus on a type-II two Higgs doublet model (2HDM-II) and consider a heavy charged Higgs with its…

The level of sensitivity of the processes $\gamma\gamma \to ZZ$, $\gamma\gamma \to W^+W^-$ and $\gamma\gamma \to t\bar t$ to the Higgs sector of the Standard Model Lagrangian in the energy region between 200 GeV and 1 TeV is examined. The…

This paper shortly reports on the results of Higgs boson searches performed at LEP and Tevatron. No signal is found and limits on the mass and couplings of the Higgs boson are derived. Interpreting the data in the framework of the Standard…

The current Large Hadron Collider data indicates that the newly observed resonance has the WW and ZZ modes consistent with the standard model Higgs boson, while the \gamma\gamma mode is about 1.2 - 2 times that of the standard model…

More evidences have now been collected at the Large Hadron Collider suggesting the new 125 - 126 GeV boson is likely the long sought Higgs boson in the standard model. One pressing question continued being asked by theorists is whether this…

We evaluate, in a model-independent way, the signal-to-background ratio for Higgs -> b bbar detection in exclusive double-diffractive events at the Tevatron and the LHC. For the missing-mass approach to be able to identify the Higgs boson,…

We present the study of the SM Higgs properties obtained from the combined analysis of the up-to 10 fb$^{-1}$ dataset collected by the CDF and D0 experiments during the $p\bar{p}$ collision at $\sqrt{s}=1.96$~TeV of Tevatron Run II. The…

We exploit the spin and kinematic correlations in the decay of a scalar boson into a pair of real or virtual W-bosons, with both W-bosons decaying leptonically, for Higgs boson discovery at 7 TeV LHC energy with 10 fb-1 luminosity. Without…

We report on searches for the standard model Higgs boson with the CDF and D0 detectors using up to 2.7 fb$^{-1}$ of $\sqrt s=$ 1.96 TeV proton anti-proton collisions at Fermilab's Tevatron. We focus on analyses that are sensitive to low…

We discuss off-shell contributions in Higgs decays to heavy gauge bosons $H\rightarrow VV^{(*)}$ with $V\in\lbrace Z,W\rbrace$ for a standard model (SM) Higgs boson for both dominant production processes $e^+e^-\rightarrow ZH\rightarrow…

In these proceedings I cover the latest results on the production and decay of the recently discovered Higgs boson. While the spin and properties of the new boson, such as its mass and couplings to bosons and fermions, are covered in a…

The Z-pole data from e+e- colliders and results from the NuTeV experiment at Fermilab can be brought into agreement if (1) the neutrino-Z couplings were suppressed relative to the Standard Model (SM), and (2) the Higgs boson were much…

A method using jets is investigated for detecting the Higgs boson at LHC in the mass range about 114 \GeVc2, suggested by LEP experiments. Higgs bosons are produced in association with a $t \bar{t}$ pair, and both t and $\bar{t}$ decay…

Tantalizing hints of the Higgs boson of mass around 125 GeV have been reported at the LHC. We explore the MSSM parameter space in which the 125 GeV state is identified as the heavier of the CP even Higgs bosons, and study two scenarios…
