On the origin of like-sign dimuons in neutrino-nucleon and antineutrino-nucleon interactions

The so-called quasi-parton mechanism is considered taking into account nonperturbative effects in QCD and enabling one to explain like-sign dimuon production inv _μ( \(\bar v_\mu\) )N interactions. The rates of production cross sections of like-sign dimuons and trimuons of nonelectromagnetic origin to inclusive cross sections, as well as the average kinematical characteristics of the fast muon are obtained. The contribution of quasi-parton mechanism in γN, μN, π^± p,pp channels is considered. The energy distribution for slow muon inv _μ N interaction is received.
