Applying the POWHEG method to top pair production and decays at the ILC.

Abstract

We study the effects of gluon radiation in top pair production and their decays for e+e− annihilation at the ILC. To achieve this we apply the POWHEG method and interface our results to the Monte Carlo event generator Herwig++. We consider a center-of-mass energy of ps = 500 GeV and compare decay correlations and bottom quark and anti-quark distributions before hadronization.
