On the associate production of a neutral intermediate-mass Higgs boson with a single top quark at the LHC and SSC

Abstract

The typical behaviour of the semiweak single top quark production mechanism in hadron-hadron collisions in comparison with heavy quark pair production suggests that boson-gluon fusion may lead to important associated Higgs cross-sections. This is of particular interest for the interval in which the Higgs mass is close to the mass of the Z 0 and well below 2 M Z 0 . In this region experimentally significant signals are expected to be small, while complicated to extract due to large backgrounds. In two recent papers, studies have been presented in which contradicting results have been reported on the magnitude of Higgs production in association with a single top quark. We present an independent analysis and trace the origin of the discrepancies.
