Signatures of Higgs Bosons in the Top Quark Decay Channel at Hadron Colliders
نویسنده
چکیده
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 in the tt̄ invariant-mass spectrum, and the spin-spin correlation studied by us is also sensitive to a Higgs boson if this particle has a sizeable pseudoscalar component. PACS number(s): 14.65.Ha, 14.80.Bn, 14.80.Cp 1 supported by BMBF contract 057AC9EP.

Top quark decays into neutral Higgs bosons and gluon in the MSSM
Flavour changing neutral decays of the top quark are know to be extremely suppressed in the SM. This is especially so for the top quark decay into the SM Higgs boson, whose rate is less than 10. However, it turns out that the decay modes t → c h, with h ≡ h, H, A any of the MSSM neutral Higgs bosons, can be much more gifted. In particular, the rate into the lightest CP-even Higgs boson h – whic...
متن کاملThe phenomenology of top quark polarisation in the decay of heavy charged Higgs bosons at LHC and beyond
It has recently been shown that through the τν decay mode the heavy charged Higgs bosons H can be discovered at LHC over a vast region of the parameter space previously thought unaccessible. If the charged Higgs bosons are discovered in this decay mode and the measurements of its mass and tan β are made, it allows us to make greater use of the dominant but Qcd background contaminated bt decay m...
متن کاملQCD Corrections to Scalar Production via Heavy Quark Fusion at Hadron Colliders
We recently proposed that, due to the top-quark-mass enhanced Yukawa coupling, the s-channel production of a charged scalar or pseudo-scalar from heavy quark fusion can be an important new mechanism for discovering non-standard spin-0 particles. In this work, we present the complete O(αs) QCD corrections to this s-channel production process at hadron colliders, and also the results of QCD resum...
متن کاملHiggs Decay to Top Quarks at Hadron Colliders
Higgs bosons which decay principally to top quarks, such as in the minimal supersymmetric model, produce a peak-dip structure in the gg → tt̄ invariant-mass spectrum. This structure is potentially observable at the CERN Large Hadron Collider.
متن کاملFCNC top quark decays in the MSSM: a door to SUSY physics in high luminosity colliders?
We study the FCNC top quark decays t→ c h in the framework of the MSSM, where h ≡ h, H, A is any of the supersymmetric neutral Higgs bosons. We include the leading set of SUSY-QCD and SUSY electroweak contributions. While the FCNC top quark decay into the SM Higgs boson has such a negligible rate that will not be accessible to any presently conceivable accelerator, we find that there is a chanc...
