The amplitudes are calculated with factorization approach, and the transition form factors $A_0^{B^{\\ast}_{(s)}\\to M_1}(0)$ are evaluated within BSW model. With the reasonable approximation $\\Gamma_{tot}(B^*_{(s)})\\simeq \\Gamma(B^*_{(s)}\\to B_{(s)}\\gamma)$, our predictions of branching fractions are presented. Numerically, the CKM-favored tree-dominated $\\bar{B}^{*0} \\to D^+D^-_s$ and $\\bar{B}^{*0}_s \\to D^+_sD^-_s$ decays have the largest branching fractions of the order $\\sim{\\cal O}(10^{-8})$, and hence will be firstly observed by forthcoming Belle-II experiment. However, most of the other decay modes have the branching fractions~$<{\\cal O}(10^{-9})$ and thus are hardly to be observed soon. Besides, for the possible detectable $B^{\\ast}_{(s)}$ decays with branching fractions $\\gtrsim{\\cal O}(10^{-9})$, some useful ratios, such as $R_D$ {\\it et al.,} are presented and discussed in detail.", "revisions": [ { "version": "v1", "updated": "2016-05-05T15:49:26.000Z" } ], "analyses": { "subjects": [ "12.39.St" ], "keywords": [ "factorization approach", "weak decays", "nonleptonic", "heavy flavor physics", "transition form factors" ], "tags": [ "journal article" ], "publication": { "publisher": "World Scientific" }, "note": { "typesetting": "TeX", "pages": 17, "language": "en", "license": "arXiv", "status": "editable", "inspire": 1396911 } } }
