Enhanced Three-Body Decay of the Charged Higgs Boson
If the charged Higgs boson H+ exists with mH+ < mt+mb, the conventional expectation is that it will decay dominantly into cs̄ and τντ . However, the three-body decay mode H+ → W+bb̄ is also present and we show that it becomes very important in the low tan β region for mH+ ∼ > 140 GeV. We then explore its phenomenological implications for the charged-Higgs-boson search in top-quark decay. The disc...
متن کاملQCD and SUSY-QCD corrections to the Three-Body Decay of the Charged Higgs Boson
The O(αs) QCD corrections to the three-body decay width of the charged Higgs Γ(H+ →W+bb̄) are discussed in the MSSM model. Our calculations indicate that the standard QCD corrections to the three-body decay mode raise the width by about 12% and the supersymmetric QCD corrections(due to g̃, t̃, b̃ exchanges) can be comparable to or even larger than the standard QCD corrctions in some regions of the ...
متن کاملLooking for the Charged Higgs Boson
This review article starts with a brief introduction to the charged Higgs boson (H) in the Minimal Supersymmetric Standard Model (MSSM). It then discusses the prospects of a relatively light H boson search via top quark decay at Tevatron/LHC, and finally a heavy H boson search at LHC. The viable channels for H search are identified in both the cases, with particular emphasis on the H → τν decay...
متن کاملHiggs-boson decay into photons
We compute the dominant two-loop electroweak correction, of O(GFM t ), to the partial width of the decay of an intermediate-mass Higgs boson into a pair of photons. We use the asymptotic-expansion technique in order to extract the leading dependence on the top-quark mass plus four expansion terms that describe the dependence on the W and Higgs-boson masses. This correction reduces the Born resu...
