Trimuon and Like-Sign—Dimuon Production in Neutrino Scattering

Abstract
Model calculation based on associated production of charmed (and new) hadrons is presented for the characteristics of trimuon and like-sign—dimuon production in neutrino scattering. They are in general agreement with the qualitative features of the data. Discussions are given with emphasis on comparing the present model with the model based on sequential decays of heavy leptons.
