Abstract
We analyze from a theoretical point of view the impact of various appr oximations on W mass distributions. This is done both at parton level and after a simulated W mass reconstruction using constrained fits. Th e results may help to understand the origin of various shifts and the broadening of the peak in direct reconstruction mass measurements. (C) 1998 Elsevier Science B.V.
