TL;DR

This study estimates the total yields of specific strange particles in neutrino-induced reactions at around 10 GeV, revealing their production characteristics and energy dependence, and comparing with higher energy data.

Contribution

First estimation of total yields of $K^+(892)$, $\Sigma^+(1385)$, and $\Sigma^0$ in neutrino reactions at moderate energies using SKAT data.

Findings

$K^+(892)$ yield increases approximately linearly with energy.

$\Sigma^0$ yield increases approximately logarithmically with energy.

Decay contributions to $K^0$ and $\Lambda$ yields align with higher energy data.

Abstract

Using the data obtained with SKAT bubble chamber, the total yields of $K^+(892)$, $\Sigma^+(1385)$ and $\Sigma^0$ are estimated for the first time in neutrino-induced reactions at moderate energies ($<E_{\nu}>$ = 10.4 GeV). It is shown, that the recently observed \cite{ref1,ref2} enhancement of the $K^0$ and $\Lambda$ yields in $\nu A$ interactions (as compared to $\nu N$ interactions) is contributed only slightly by the $K^+(892)$ and $\Sigma^+(1385)$ production, respectively. The decay contribution to the $K^0$ and $\Lambda$ yields is found to be in qualitative agreement with higher energy ($<E_\nu> \geq$ 40 GeV) data. It is shown, that the energy dependence of the $K^+(892)$ mean multiplicity in $\nu N$ interactions is approximately linear in the range of $<E_{\nu}> \approx$ 10-60 GeV, while that for $\Sigma^0$ in $\nu A$ interactions (for $A$ = 20-21) is approximately logarithmic in the range of $<E_{\nu}> \approx$ 10-150 GeV.
