Charm and dilepton production by neutrinos and antineutrinos

Abstract

A review of charm and dilepton production by neutrinos and antineutrinos is presented. A brief status of same sign dileptons is given followed by a detailed review of opposite sign data. Combined results for the three experiments, CCFR, CDHS and FMMF, are used to extract the strange sea content in the nucleon, $\text{κ = 2s/(}\text{u}\text{+}\text{d}\text{) = .492 ± .06}$ and the CKM matrix element, |V_cd| = .204 ± .012. Preliminary results from the CCFR collaboration show that the x distribution of the strange sea is softer than the $\text{u}$ and $\text{d}$ sea and that the slow rescaling model describes the energy dependence of the charm cross section well with a charm mass of m_c = 1.34 ± 0.33GeV/c².
