Weak B Decays into Orbitally Excited Charmed Mesons

High Energy Physics - Phenomenology 2020-05-19 v1

Abstract

The BaBar Collaboration has recently reported branching fractions for semileptonic decays of the BB meson into final states with charged and neutral D1(2420)D_{1}(2420) and D2(2460)D_{2}^{\ast}(2460), two narrow orbitally excited charmed mesons. We evaluate these branching fractions within the framework of a constituent quark model in two steps, one which involves a semileptonic decay and the other one mediated by a strong process. Our results are in agreement with the experimental data.
