Update on strong and radiative decays of the D_s0^*(2317) and D_s1(2460) and their bottom cousins

The isospin breaking and radiative decay widths of the positive-parity charm-strange mesons, D^*_s0 and D_s1 , and their predicted bottom-strange counterparts, B^*_s0 and B_s1 , as hadronic molecules are revisited. This is necessary, since the B^*_s0 and B_s1 masses used in (Cleven et al., Eur Phys J A 50:149, 2014) were too small, in conflict with the heavy quark flavour symmetry. Furthermore, not all isospin breaking contributions were considered. We here present a method to restore heavy quark flavour symmetry, correcting the masses of B^*_s0 and B_s1 , and include the complete isospin breaking contributions up to next-to-leading order. With this we provide updated hadronic decay widths for all of D^*_s0 , D_s1 , B^*_s0 and B_s1 . Results for the partial widths of the radiative deays of D_s0^*(2317) and D_s1(2460) are also renewed in light of the much more precisely measured D^*+ width. We find that B_sπ ^0 and B_sγ are the preferred channels for searching for B_s0^* and B_s1 , respectively.
