Dalitz decays of vector heavy quarkonia into $χ_{Q J} (1 P)$ in the Bethe-Salpeter approach

Xin-Wen Wang, Wen-Yuan Ke, Su-Yan Pei +3

We systematically investigate the Dalitz decays of vector heavy quarkonia into $χ_{Q J} (1 P) ℓ^{+} ℓ^{-}$ ( $Q = c, b$ ; $J = 0, 1, 2$ ; $ℓ = e, μ$ ) within the instantaneous Bethe--Salpeter fr…

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…

Relativistic effects in the strong and electromagnetic decays of $D^{*}$ meson

Man Jia, Wei Li, Su-Yan Pei +3

In this paper, we solve the complete Salpeter equation and use the obtained relativistic wave function to calculate the strong and radiative electromagnetic decays of the $D^{*}$ m…

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…
