TL;DR

This paper discusses the reconstruction efficiency and detection strategies for $ ext{Lambda}$ and $ ext{Sigma}^+$ hyperons in p+C interactions at 10 GeV/c, highlighting observed resonances and their implications.

Contribution

It introduces a method for hyperon reconstruction efficiency assessment and reports the observation of specific hyperon resonances in experimental data.

Findings

Lambda hyperon reconstruction efficiency is 16%

Observation of $ ext{Sigma}^{*+}$(1385) resonance

Detection of $ ext{Sigma}^+$(1620) resonance

Abstract

The efficiency for multi-strange hyperon reconstruction and the detection strategy for basic kinematic parameters are described using experimental data of p+C interaction at 10 GeV/c. The efficiency for $\Lambda$ hyperon reconstruction is equal to 16%. The $\Sigma^{*+}$(1385)and $\Sigma^+$(1620) resonances are observed in the reconstructed $\Lambda \pi^+$ mass spectrum.
