QUARK MODEL AND NEUTRAL STRANGE SECONDARY PRODUCTION BY NEUTRINO AND ANTINEUTRINO BEAMS

The experimental data on K and Λ production by ν and ν̄ beams are compared with the predictions of quark model assuming that the direct production of secondaries dominates. Disagreement of these predictions with the data allows one to suppose that there exists considerable resonance decay contribution to the multiplicities of produced secondaries.
