The Preliminary Result from ($K_s^0{\pi }^{\pm }$) Spectra in p+a Reaction at 10 Gev/C

Abstract

The experimental data from 2m propane bubble chamber have been analyzed to search of scalar meson $\kappa$(800) in $K_s^0{\pi }^{\pm }$ spectra for the reaction p+A at 10 GeV/c. The $K_s^0{\pi }^{\pm }$ invariant mass spectra has shown similarly resonant structures with $M_{K_s^0\pi }$=720,780 and 890 MeV/$c^2$. The M(890) peak is identified as the well known resonance $K^{\ast }$ from PDG.
