Improved covariant analysis of $B_{c}^{+} \to χ_{c 1} (n P)$ decays and implications for the nature of $χ_{c 1} (3872)$

Shi-Hang Zhang, Jia-Yi Zheng, Wei Li +5

We study the weak decays $B_{c}^{+} \to χ_{c 1} (n P) ℓ^{+} ν_{ℓ}$ and $B_{c}^{+} \to χ_{c 1} (n P) X$ (n=1,2,3) within the Bethe-Salpeter formalism, treating $χ_{c 1} (3872)$ as the conventional $χ…

Kinetic energy and speed powers $v^{n}$ of a heavy quark inside $S$ wave and $P$ wave heavy-light mesons

Wei Li, Tianhong Wang, Tai-Fu Feng +2

Based on the instantaneous Bethe-Salpeter equation method, we calculate the average values $∣ q ∣^{n} \equiv q^{n}$ and speed powers $∣ v ∣^{n} \equiv v^{n}$ (…

The decay property of the $X (3842)$ as the $ψ_{_{3}} (1^{3} D_{_{3}})$ state

Wei Li, Su-Yan Pei, Tianhong Wang +2

In this paper, the new particle $X (3842)$ discovered by the LHCb Collaboration is identified to be the $ψ_{_{3}} (1^{3} D_{_{3}})$ state. We study its strong decays with the combination of…
