英文摘要	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-s pi(0) and B-s gamma are the preferred channels for searching for B-s0* and B-s1, respectively.
