Higgs Bosons Strongly Coupled to the Top Quark
Several extensions of the Standard Model require the burden of electroweak symmetry breaking to be shared by multiple states or sectors. This leads to the possibility of the top quark interacting with a scalar more strongly than it does with the Standard Model Higgs boson. In top-quark condensation this possibility is natural. We also discuss how this might be realized in supersymmetric theorie...
متن کاملOn the Charged Higgs Bosons Effects in the Top Quark Decays
The collider experiments at the Tevatron and the LHC provide us the possibility of probing the existence of a light charged Higgs boson. In this paper we study semi-leptonic decay of a polarized top quark via the charged Higgs boson (t(↑) → Hb → lνlb). It is shown that the asymmetry or spin correlation coefficient of the charged lepton depends on the tanβ andMH± and is quite different from the ...
متن کاملLight Higgs bosons from a strongly interacting Higgs sector
The mass and the decay width of a Higgs boson in the minimal standard model are evaluated by a variational method in the limit of strong self-coupling interaction. The non-perturbative technique provides an interpolation scheme between strong-coupling regime and weak-coupling limit where the standard perturbative results are recovered. In the strong-coupling limit the physical mass and the deca...
متن کاملSignatures of Higgs Bosons in the Top Quark Decay Channel at Hadron Colliders
We analyze some signatures of neutral Higgs bosons, produced in high energy proton (anti)proton collisions, which decay primarily to top quarks. This channel is clouded by a large irreducible tt̄ background. We investigate the tt̄ invariant-mass distribution in the lepton+jets decay mode of tt̄ and a tt̄ spin-spin correlation in the dilepton decay mode. At the LHC such Higgs bosons can be detected ...
