Leptonic Decays of Heavy Vector and Pseudoscalar Mesons
Pure leptonic decays of D＊0（B＊a, B＊d） - l＋l- and D±＊（D＊a, B＊＋, B＊c） -＋ lvz are investigated. The hadronic contributions such as Do --＋ D＊0-y --＋ μ＋μ- axe also explored. We then obtain the updated branching fractions of the pseudoscalax mesons to lepton pairs axe modified by a factor of few percentag...

| Summary: | Pure leptonic decays of D＊0（B＊a, B＊d） - l＋l- and D±＊（D＊a, B＊＋, B＊c） -＋ lvz are investigated. The hadronic contributions such as Do --＋ D＊0-y --＋ μ＋μ- axe also explored. We then obtain the updated branching fractions of the pseudoscalax mesons to lepton pairs axe modified by a factor of few percentages. Specifically, the Br（B＋ --＋ e＋Vc） is reduced by a factor 13%. |
