Possible interpretation of the newly observed

Inspired by the newly observed b states by the LHCb Collaboration, we investigate the two-body strong decays of the low-lying.-mode b baryons up to N = 2 shell using the chiral quark model within the j - j coupling scheme. Our results indicate that: (i) the newly observed states b(6316)- and b(6330)- are good candidates of the light spin j = 1 states, while the spin-parity J P = 1/2and J P = 3/2- cannot be distinguished. The other two states, b(6340) and b(6350) mostly correspond to the light spin j = 2 states, while the spin-parity J P = 3/2- and J P = 5/2- cannot be distinguished as well. (ii) The 2S states with spin-parity J P = 1/2+ and J P = 3/2+, respectively, might be narrow states with a width of < 2 MeV. (iii) The 1D states are not broad and the total decay widths vary from several to dozens of MeV, which have a good potential to be observed in future experiments.
