Abstract

We present theoretical predictions for the hadroproduction of tt¯ + bb¯ final state matching numerical computations at NLO accuracy in QCD with shower Monte Carlo programs. We propose to use half of the sum of transverse masses as renormalization and factorization scales, which gives small NLO K-factor and scale dependence. The events stored according to the Les Houches accord can be used as input in shower Monte Carlo programs to simulate parton showering and hadronization. We show that the decay of the heavy particles may affect the kinematic distributions most, while the changes due to PS and hadronization are small except in regions dominated by Sudakov suppression.
