Reconstruction and approximation effects on W mass distributions at LEP2
arXiv:hep-ph/9710282 · doi:10.1016/S0370-2693(98)00056-2
Abstract
We analyze from a theoretical point of view the impact of various approximations on W mass distributions. This is done both at parton level and after a simulated W mass reconstruction using constrained fits. The results may help to understand the origin of various shifts and the broadening of the peak in direct reconstruction mass measurements.
