Associated Higgs production with bottom quarks at hadron colliders
نویسنده
چکیده
Higgs-boson production in association with bottom quarks, pp̄/pp→ bb̄H+X, is an important discovery channel for supersymmetric Higgs particles at the Tevatron and the LHC. We present higher-order QCD predictions for inclusive cross sections and for the production of a Higgs boson in association with high-pT bottom quarks. We compare calculations performed in a four-flavour scheme based on the parton processes gg, qq̄ → bb̄H with five-flavour scheme calculations based on bottom-quark scattering.

Double Parton Scattering in Associate Higgs Boson Production with Bottom Quarks at Hadron Colliders
Higgs boson production in association with bottom quarks, is one of the most important discovery channels for Higgs particles in the Standard Model (SM) and its supersymmetric extension at the LHC pp collider . The theoretical prediction of the corresponding cross section has been improved by including the complete next-to-leading order QCD corrections. We review the status results for the lead...

We present the calculation of Next-to-Leading-Order Quantum Chromo Dynamics corrections for the production of a W or Z weak boson associated with a bottom anti-bottom quark pair at hadron colliders (pp̄, pp → W/Z bb̄), including the effects of a non-zero bottomquark mass. We find a considerable reduction of the renormalization and factorization scale dependence of our results with respect to Lead...
متن کاملAssociated production of Higgs bosons and heavy quarks at photon colliders
The idea of fermion mass generation through Yukawa couplings between Higgs bosons and fermions may be tested by their associated production at future linear colliders ( LC ). We study the production mechanism in the minimal supersymmeric standard model at photon colliders that can be realized by the laser back-scattering technique at the LC. We find that the cross sections for the production of...
متن کاملHiggs Boson Production in Association with Scalar Top Quarks at Proton Colliders
We investigate the production of Higgs particles in association with the supersymmetric scalar partners of the top quark at proton colliders. In the minimal supersymmetric extension of the Standard Model, the cross sections for the production of the lightest neutral Higgs boson in association with top squark pairs can be rather large, substantially exceeding the rate for the associated Higgs bo...
متن کاملProbing Higgs Bosons with Large Bottom Yukawa Coupling at Hadron Colliders
The small mass of the bottom quark, relative to its weak isospin partner, the top quark, makes the bottom an effective probe of new physics in Higgs and top sectors. We study the Higgs boson production associated with bottom quarks, pp̄/pp → φbb̄ → bb̄bb̄, at the Fermilab Tevatron and the CERN LHC. We find that strong and model-independent constraints on the size of the φ-b-b̄ coupling can be obtain...
