Multimuon production in deep-inelasticμ-nucleus scattering

Abstract

Multimuon production in deep-inelastic $\mu$-nucleus scattering is estimated using the quarkparton model and the assumption that the secondary muons come from the production of a charmed-particle-antiparticle pair out of the $c\overline{c}$ pair in the sea of the nucleon and the subsequent semileptonic decay of these charmed particles. The calculated $x$, $y$, and $Q^2$ distributions are in agreement with the preliminary data reported by Chen of the Cornell-Michigan State-UCB-UCSD group.
