Strong decays of the newly observed narrow Ωb structures

Motivated by the newly observed narrow structures Omega(b)(6316)(-), Omega(b)(6330)(-), Omega(b)(6340)(-), and Omega(b)(6350)(-) in the Xi K-0(b)- mass spectrum, we investigate the strong decays of the low-lying Omega(b) states within the P-3(0) model systematically. According to their masses and decay widths, the observed Omega(b)(6316)(-), Omega(b)(6330)(-), Omega(b)(6340)(-), and Omega(b)(6350)(-) resonances can be reasonably assigned as the lambda-mode Omega(b)(1P) states with J(P)=1/2(-),3/2(-),3/2(-), and 5/2(-). Meanwhile, the remaining P-wave state with J(P)=1/2(-) should have a rather broad width, which can hardly be observed by experiments. For the Omega(b)(2S) and Omega(b)(1D) states, our predictions show that these states have relatively narrow total widths and mainly decay into the Xi(b)(K) over bar, Xi(')(b)(K) over bar, and Xi('*)(b)(K) over bar final states. These abundant theoretical predictions may be valuable for searching more excited Omega(b) states in future experiments.
