Energy of W distribution in top quark decays
M. Jeżabek, C. Jünger
Abstract
A relatively simple analytical formula is derived for the energy spectrum of W boson in top quark decays t Wb including O(αs) radiative corrections. We discuss the accuracy of this formula and compare it to a more general albeit more complicated one derived in CJK~. A Monte Carlo algorithm for generation of W energy spectrum is briefly described.
