On the determination of M_W and TGCs in W-pair production using the best measured kinematical variables

摘要

A study is made of the feasibility of maximum likelihood fits to determineM_W and triple gauge boson couplings using only those experimental kinematicalvariables that are well measured. A computational tool to calculate theoreticalprobabilities for those kinematical variables is discussed and then applied tosamples of unweighted events produced by an event generator. Detailed resultson the M_W determination for semileptonic final states in W-pair productionshow the feasibility of the method. For TGCs one result is presented as anillustration.
