| dc.description | Experimental data from the 2m propane bubble chamber have been analyzed to search for an exotic baryon states, in the $ΛK^0_s$ decay mode for the reaction p+$C_3H_8$ at 10 GeV/c. The invariant mass spectrum $ΛK^0_s$ observe a narrow peaks at 1750$\pm$18, 1795$\pm$18,1850$\pm19$ MeV/$c^2$ and full widths of $Γ_{exp.}$= 32$\pm$6, 44$\pm$15, 29.0$\pm$8 MeV/$c^2$. The statistical significance of these peaks has been estimated as 5.6, 3.3 and 3.0 S.D., respectively. There are the small enhancements in mass regions of (1650-1675) and (1925-1950) МэВ/с$^2$. These would be candidates for the $N^0$ or the $Ξ^0$ pentaquark states. The investigation has been performed at the Veksler and Baldin Laboratory of High Energies, JINR. | |
