ON THE DETERMINATION OF MW AND TGCs IN W -PAIR PRODUCTION USING THE BEST MEASURED KINEMATICAL VARIABLES

Abstract A study is made of the feasibility of maximum likelihood fits to determine M W and triple gauge boson couplings using only those experimental kinematical variables that are well measured. A computational tool to calculate theoretical probabilities for those kinematical variables is discussed and then applied to samples of unweighted events produced by an event generator. Detailed results on the M W determination for semileptonic final states in W -pair production show the feasibility of the method. For TGCs one result is presented as an illustration.
