Dimuon production in neutrino and antineutrino interactions

Thesis/Dissertation ·
OSTI ID:5445447
Results are presented, obtained by the HPWF group at Fermi Lab, for the production rates and general characteristics of dimuon events arising from neutrino and antineutrino interactions with nucleons. The data sample consists of 769 neutrino interactions, 181 antineutrino interactions, and 176 same sign events. The rates for both the prompt and nonprompt dimuon signals for opposite sign events and for neutrino induced same sign events are determined in a manner that is independent of any theoretical assumptions. The dependence of the rates on neutrino energy is also presented. The measured rate for prompt like sign dimuon production is shown to be incompatible with theoretical predictions. Various kinematical distributions are shown which demonstrate the good agreement between the theoretical predictions for dimuons arising from the production of charmed quarks and the observed data. Kinematical distributions for the same sign events are presented that indicate that the two muons are produced at different space time points. The data indicate that one of muons in a same sign event is associated with the incoming neutrino and that the other muon is associated with the hadronic shower.
