| dc.description | The 2m propane bubble chamber experimental data have been analyzed to search for an exotic baryon state, the $Θ^+$ -baryon, in the $pK^0_s$ decay mode for the reaction p+$C_3H_8$ at 10 GeV/c. The $pK^0_s$ invariant mass spectrum shows resonant structures with $M_{K_s^0 p}$=1540$\pm$8, 1613$\pm$10, 1821$\pm$11 MeV/$c^2$ and $Γ_{K_s^0 p}$= 9.2$\pm$1.8, 16.1$\pm$4.1, 28.0$\pm$9.4 MeV/$c^2$. The maximal statistical significance of these peaks have been estimated as 5.5$σ$,4.8$σ$ and 5.0$σ$, respectively. | |
