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.
