Abstract

In this article we describe simulations of the hadronic decay of Higgs bosons produced in association with vector bosons at linear and hadronic colliders. We use the Monte Carlo at next-to-leading-order MC@NLO matching prescription with the Herwig++ event generator to predict various spectra of the resulting b anti-b pairs and compare our results with leading order and matrix element correction predictions.
