摘要
We study the Higgs boson effects on third-generation squark-pair production in proton-proton collision at the CERN Large Hadron Collider (LHC), includinget tt *, tb*, and bb *. We found that substantial enhancement can be obtained through s-channel exchanges of Higgs bosons at large tan β, at which the enhancement mainly comes from bb̄, bc̄ and cb̄ initial states. We compute the complete set of electroweak (EW) contributions to all production channels. This completes previous computations in the literature. We found that the EW contributions can be significant and can reach up to 25% in more general scenarios and at the resonance of the heavy Higgs boson. The size of Higgs enhancement is comparable or even higher than the parton distribution functions uncertainties and so must be included in any reliable analysis. © 2010 SISSA.
