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

Authors

Description

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