Under the suggested assignment, the masses and total decay widths of $\\Lambda_b(6146)^0$ and $\\Lambda_b(6152)^0$ can be explained. As a $J^P=3/2^+$ state, the $\\Lambda_b(6146)^0$ should mainly decay into $\\Sigma_b(5815)\\pi$. However, this theoretical result is in contradiction to the measurement since no significant $\\Lambda_b(6146)^0\\rightarrow\\Sigma_b(5815)^\\pm\\pi^\\mp$ signals were observed by the LHCb.
