Associated production of the Higgs boson and a single top quark at hadron colliders - art. no. 094023

We study the production of the Higgs boson in association with a single top quark at hadron colliders. The cross sections for the three production pro cesses (t channel, s channel, and W associated) at both the Fermilab Tevatr on and the CERN Large Hadron Collider (LHC) are presented. We investigate t he possibility of detecting a signal for the largest of these processes, th e t-channel process at the LHC, via the Higgs boson decay into b (b) over b ar. The QCD backgrounds are large and difficult to curb, hindering the extr action of the signal. Extensions of our analysis to the production of super symmetric Higgs bosons are also addressed. The cross section is enhanced fo r large values of tan beta, increasing the prospects for extracting a signa l.
