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 500GeV and compare decay correlations and bottom quark distributions before hadronization.6 pages, 3 figuresHigh Energy Physics - Phenomenologytext
