Abstract
In this paper, we present two programs to fit M-w at LEP2 using the best me asurable kinematical variables. The theoretical probabilities of observing the final-state kinematical configurations are computed by integrating over the quantities that are not well measured. Therefore, an event-by-event ki nematical reconstruction is avoided. M-w is then determined through a maxim um likelihood fit. (C) 1998 Elsevier Science B.V.
