Neutral strange particle production in neutrino and antineutrino charged current interactions on protons

  • Published:

Abstract

The production of the neutral strange particlesK 0, Λ and\(\bar \Lambda \) invp and\(\bar vp\) charged current interactions is studied in an experiment with the Big European Bubble Chamber. Mean multiplicities are measured as a function of the event variablesE v,W 2 andQ 2 and of the hadron variablesx F,z andp 2T .K (892) and (1385) signals are observed, whereas there is no evidence for *- (1385) production invp scattering. Forward, backward and total mean multiplicities are found to compare well with the predictions of an empirical model for deep-inelastic reactions in the case of the strange mesonsK 0 andK (892) but less so for the strange baryons Λ,\(\bar \Lambda \) and (1385). The strange baryon multiplicities are used to obtain the decuplet to octet baryon production ratio and to assess the probabilities of auu orud system to break up.
