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…

Radiative transitions of $I ¨ _{_{c J}} \to I ¨ I^^{3}$ and $I ¨ _{_{b J}} \to I^¥ I^^{3}$

Su-Yan Pei, Wei Li, Tianhong Wang +1

In the framework of instantaneous Bethe-Salpeter equation, according to the $J^{P C}$ of quarkonia, we find that their wave functions all contain multiple partial waves, rather th…

Production of $D_{s 0} (2590)^{+}$ in $B$ nonleptonic decays

Shuang-Tao Wang, Su-Yan Pei, Tianhong Wang +1

In 2021, a new charm-strange meson, $D_{s 0} (2590)^{+}$ , has been discovered, it is believed to be the $D_{s}^{+} (2^{1} S_{0})$ . However, its low mass and wide width are challenged by theoreti…

Semirelativistic study on the semileptonic decays of $B_{q}$ mesons to orbital excited heavy Tensors

Wen-Yuan Ke, Su-Yan Pei, Tianhong Wang +1

Based on the method of solving the complete Salpeter equation, we study the semileptonic decays of a $0^{-}$ heavy meson to $1 P$ , $2 P$ , or $3 P$ heavy tensor mesons, $B_q \to (\bar c…
