Abstract

Experimental results on multimuon production by neutrinos and antineutrinos from the CERN - Dortmund - Heidelberg - Saclay neutrino are presented:
  1. (a)

    257 (58) fully reconstructed opposite-sign dimuon events (antineutrinos) are interpreted as due to charm production and decay;

     
  2. (b)

    28 trimuon (μμμ+) events are compared to different models assuming an electromagnetic, hadronic or purely leptonic origin of the events. The data point towards hadronic μ-pair production as the main source of trimuons;

     
  3. (c)

    a first tetramuon event ν + N μ μ+μμ+ X has been observed.
