DOIAbstract
The authors discuss the contribution of associated production of charmed pairs cc to multilepton events in nu reactions, with emphasis on like-sign dimuons and trimuons. Both absolute rates and constraints from distributions are considered. They give one treatment which is purely phenomenological, obtaining the maximum amount of cc production which can be consistent with existing data on distributions, and giving relative amounts for different multilepton states. They also attempt a theoretical analysis which gives an estimate for the magnitude of cc production in nu reactions starting from photoproduction of psi ; this leads to a rate significantly larger than that due to perturbative quantum-chromodynamics estimates made so far.
