Numerical analysis of the production of $D^{(*)}(3000)$, $D_{sJ}(3040)$ and their partners through the semileptonic decays of $B_{(s)}$ mesons in terms of the light-front quark model

TL;DR

This paper uses the light-front quark model to analyze the production of newly observed $D^{(*)}(3000)$ and $D_{sJ}(3040)$ states via semileptonic $B_{(s)}$ decays, predicting sizable branching ratios for future experimental detection.

Contribution

It provides the first detailed theoretical analysis of $D^{(*)}(3000)$ and $D_{sJ}(3040)$ production in $B_{(s)}$ decays using the light-front quark model, highlighting potential observability.

Findings

Significant branching ratios for $B_{(s)}$ decays into $2P$ charmed states.

Predictions suggest these decays are accessible at LHCb and Belle II.

The study supports experimental searches for these states in semileptonic decays.

Abstract

Inspired by the newly observed $D^{(*)}(3000)$, and $D_{sJ}(3040)$ states, in this work we study the production of $D^{(*)}(3000)$, $D_{sJ}(3040)$ and their partners through the semileptonic decays of $B_{(s)}$ mesons, where the light-front Quark model is applied to the whole calculation. Our numerical results indicate that the $B_{(s)}$ 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.
