Productions of $T_{cc}$ and its SU(3)-flavor symmetry and heavy quark spin symmetry partners in $B_{c}$ decays

Yi Zhang, Ming-Zhu Liu, Li-Sheng Geng

Inspired by the observation of the doubly charmed tetraquark state $T_{cc}$ at $pp$ collisions in the inclusive processes, we systematically investigate the production of doubly ch…

$V_{c b}$ puzzle in semi-leptonic $B \to D^{*}$ decays revisited

Shuang-Yi Li, Jie Xu, Rui-Xiang Shi +2

Inspired by the newly reported $B \to D^{*} (\to D π) ℓ ν ˉ_{ℓ}$ differential decay rates by the Belle and Belle II Collaborations, we revisit the $V_{c b}$ puzzle in semi-leptonic $…

$B_{(s)} \to S (a_{0} (1450), K_{0}^{*} (1430), f_{0} (1500))$ helicity form factors within QCD light-cone sum rules

Yi Zhang, Wei Cheng, Jia-Wei Zhang +3

In this paper, we investigate the helicity form factors (HFFs) of the $B_{(s)}$ -meson decay into a scalar meson with a mass larger than 1~GeV, {\it i.e.,} $B \to a_{0} (1450)$ , $B_{(s…
