Quark Model and Neutral Strange Secondary Production by Neutrino and Antineutrino Beams

TL;DR

This paper compares experimental data on neutral strange particle production by neutrino and antineutrino beams with quark model predictions, suggesting resonance decay significantly contributes to secondary production.

Contribution

It highlights the discrepancy between quark model predictions and experimental data, proposing resonance decay as a key factor in secondary particle multiplicities.

Findings

Disagreement between model and data indicates additional resonance decay contributions.

Resonance decay plays a significant role in neutral strange secondary production.

Quark model alone cannot fully explain experimental multiplicities.

Abstract

The experimental data on $K^0$ and $\Lambda$ production by $\nu$ and $\bar{\nu}$ 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.
