Obsevation of exotic resonances for K0(short)pi,K0(short)p and K0(short)Lambda spectra in p+A collisions at 10 GeV/c

TL;DR

This paper reports on the analysis of p+A collision data at 10 GeV/c, revealing resonant structures in $K^0_s$ spectra that suggest potential exotic baryon and meson states, expanding understanding of hadronic resonances.

Contribution

It presents new experimental evidence of resonant structures in $K^0_s$ spectra, indicating possible exotic baryon and meson states in p+A collisions at 10 GeV/c.

Findings

Resonant structures observed in $K^0_s o ext{pi}$, $K^0_s p$, and $K^0_s \Lambda$ spectra.

Possible identification of $ ext{kappa}(720)$, $ heta^+(1540)$, and $N^0(1750)$ or $\Xi^0$ states.

Validation of the method through known resonances like $\Sigma^0$, $\Sigma^{*+}(1385)$, and $K^{* ext{±}}(892)$.

Abstract

The review on the 2m propane bubble chamber experiment data analysis aimed to searches for an exotic baryon states for $K^0_s$-meson subsystems. The observation of $\Sigma^0$, $\Sigma^{*+}$(1385) and $K^{*\pm}$(892) well known resonances from PDG are a good tests of this method. There are found a resonant structures for $K^0_s\pi^{\pm}$, $K^0_s$p and $K^0_s\Lambda$ invariant mass spectra which were interpreted as $\kappa$(720)-meson, $\Theta^+(1540)$-baryon and $N^0(1750)$ or $\Xi^0$-baryon states, respectively.
