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…

Large Relativistic Corrections to Nonrelativistic $M 1$ Transitions in Heavy Quarkonium

Su-Yan Pe, Wei Li, Wen-Yuan Ke +3

As double heavy quarkonia, charmonium and bottomonium are generally considered to have small relativistic corrections and can be treated using nonrelativistic models. However, this…

Identification of $D_{2}^{} (3000)$ as the $D_{2}^{} (2^{3} P_{2})$ and exploring potential of undiscovered $2^{+}$ mesons via $B$ decays

Shi-Hang Zhang, Wen-Yuan Ke, Su-Yan Pei +4

Following the discovery of the $D_{2}^{*} (3000)$ , its mass and full width have been extensively studied. Yet its nature remains undetermined to date. Since it was discovered through no…
