We consider the production of singly charged Higgs bosons in the Higgs triplet and two Higgs doublet models. We evaluate the cross sections for the pair production and the single production of charged higgses at linear collider. The decay modes of H + and the Standard Model backgrounds are considered. We analyze the possibilities to differentiate between triplet and two Higgs doublet models.

CP-violating effects in the Higgs sector of the Minimal Supersymmetric Standard Model with complex parameters (cMSSM) are induced by potentially large higher-order corrections. As a consequence, all three neutral Higgs bosons can mix with each other. Recent results for loop corrections in the Higgs sector of the cMSSM are reviewed [1]. Results for propagator-type corrections of O(αtαs) and comp...

We analyze the constraints on a CP-violating, flavor conserving, two Higgs doublet model from the measurements of Higgs properties and from the search for heavy Higgs bosons at LHC, and show that the stronger limits typically come from the heavy Higgs search channels. The limits on CP violation arising from the Higgs sector measurements are complementary to those from EDM measurements. Combinin...

We point out that charged Higgs bosons can decay into final states different than τντ and cs̄, even when they are light enough to be produced at LEP or at the Tevatron, through a t–quark decay. These additional decay modes are overlooked in ongoing searches and alter existing lower bounds on the mass of charged Higgs bosons present in supersymmetric and two Higgs doublets models. The discovery o...

We consider the renormalisation group flow of Higgs and Yukawa couplings within the simplest non–supersymmetric two Higgs doublet extension of the Standard Model (SM). In this model the couplings are adjusted so that the multiple point principle (MPP) assumption, which implies the existence of a large set of degenerate vacua at some high energy scale Λ, is realised. When the top quark Yukawa co...

Combined constraints from the CDF and D0 Collaborations on models of the Higgs boson with exotic spin J and parity P are presented and compared with results obtained assuming the standard model value JP=0+. Both collaborations analyzed approximately 10  fb(-) of proton-antiproton collisions with a center-of-mass energy of 1.96 TeV collected at the Fermilab Tevatron. Two models predicting exotic...

Conventional wisdom is that the standard model (SM) is not the final theory but just an effective theory of a fundamental structure. The two Higgs-doublet (2HD) model is one of the simplest extension of the SM, which consist of two SU(2) scalar doublets. A discrete symmetry is often introduced to avoid a dangerous flavour-changing neutral currents (FCNC) in the 2HD model, which forbids the CP v...

The next–to–leading order predictions for the branching ratio BR(B → X s γ) are given in a generalized class of two Higgs doublets models. Included are the recently calculated leading QED corrections. It is shown that the high accuracy of the Standard Model calculation is in general not shared by these models. Updated lower limits on the mass of the charged Higgs boson in Two Higgs Doublet Mode...

We study the coupling parameter dependence of the Higgs boson mass in a chirally invariant lattice Higgs-Yukawa model emulating the same Yukawa coupling structure as in the Higgs-fermion sector of the Standard Model. Eventually, the aim is to establish non-perturbative upper and lower Higgs boson mass bounds derived from first principles, in particular not relying on vacuum stability considerat...

In superfluids the order parameter, which describes spontaneous symmetry breaking, is an analogue of the Higgs field in the Standard Model of particle physics. Oscillations of the field amplitude are massive Higgs bosons, while oscillations of the orientation are massless Nambu-Goldstone bosons. The 125 GeV Higgs boson, discovered at Large Hadron Collider, is light compared with electroweak ene...
