Finite-Width Effects in Top Quark Production at Hadron Colliders

Abstract

Production cross sections for tt̄ and tt̄j events at hadron colliders are calculated, including finite width effects and off resonance contributions for the entire decay chain, t → bW → blν, for both top quarks. Resulting background rates to Higgs search at the CERN LHC are updated for inclusive H → WW studies and for H → ττ and H → WW decays in weak boson fusion events. Finite width effects are large, increasing tt̄(j) rates by 20% or more, after typical cuts which are employed for top-background rejection.
