Masses and widths of the exotic baryons with negative parity
Description
Masses and widths of the exotic baryons with JP=3/2- in the model including 4 QQ-bar, DP- and DV-state mixing (D corresponds to decuplet, and P and V-octet of SU(3,F) flavor group) are considered in the paper. As far as the exotic baryons with minimal masses have been studied, then consideration of 4 QQ-bar-systems with quarks in the ground state is natural. Then mesons and baryons in DP- and DV-systems are to have a zero relative orbital momentum. Six baryons with negative parity: two - with JP=1/2- and three - with JP=3/2- and one - with JP=5/2-, are predicted in the model with 4 QQ-bar-, DP- and DV-state mixing for any physical state with I and S definite values. It permits to ibtain values of physical state masses similar to those observed in the experiment. To identify predicted and observed baryons, it is necessary to have information about spins and parities in the exotic baryon resonances
