Numerical analysis of the production ofD(*)(3000),D

Abstract

Inspired by the newly observed D ðÃÞ ð3000Þ and D sJ ð3040Þ states, in this work we study the production of D ðÃÞ ð3000Þ, D sJ ð3040Þ, and their partners through the semileptonic decays of B ðsÞ mesons, where the light-front quark model is applied to the whole calculation. Our numerical results indicate that the B ðsÞ semileptonic decays into the 2P states of the charmed or charmed-strange meson family have considerable branching ratios, which shows that these semileptonic decays can be accessible at future experiments, especially LHCb and the forthcoming Belle II.

Estimating the production rates of D -wave charmed mesons via the semileptonic decays of bottom mesons

“…For getting the numerical results of the discussed semileptonic decays, we adopt the light-front quark model, which has been extensively applied to study decay processes including semileptonic decays [35][36][37][38][39][40][41][42][43][44][45][46][47][48]. Our study under the framework of the LFQM shows that the whole deduction relevant to the D-wave D/D s mesons produced via B/B s mesons is much more complicated than that relevant to production of the Swave and P-wave D/D s mesons [35][36][37]. In this paper, we have given detailed derivation of many formulas necessary for obtaining the final semileptonic decay widths.…”

“…In Refs. [35][36][37][38][39][40][41][42][43][44][45][46][47][48], production rates of S -and P-wave D/D s mesons have been estimated through the decay processes of B/B s in the covariant LFQM.…”

Strong decays of $D_J(3000)$ and $D_{sJ}(3040)$

“…Therefore, the assignments of the 2P(1 + ) states are reasonable. In addition, by studying the semileptonic decay of B and B s mesons, these two candidates can also be interpreted as 2P(1 + ) states [12][13][14].…”
