Study on the weak decay between two heavy baryons $B_{i} (\frac{1}{2}^{+}) \to B_{f} (\frac{3}{2}^{+})$ in the light-front quark model

Fang Lu, Hong-Wei Ke, Xiao-Hai Liu +1

In this work, we study the weak decay between two heavy baryons $B_{i} (\frac{1}{2}^{+}) \to B_{f} (\frac{3}{2}^{+})$ in the light-front quark model where three-quark pic…

The study of possible molecular states of $D_{s}^{()} D_{s}^{()}$ and $B_{s}^{()} B_{s}^{()}$

Hong-Wei Ke, Yan-Liang Shi

Recently the LHCb collaboration reported a new exotic state $T_{cc}^{+}$ which is conjectured to be a molecular state of $D^{0} D^{*+}$ (or $D^{* 0} D^{+}$ ) theoretically. Belle Collabora…

Lifetimes of Doubly Charmed Baryons

Hai-Yang Cheng, Yan-Liang Shi

The lifetimes of doubly charmed hadrons are analyzed within the framework of the heavy quark expansion (HQE). Lifetime differences arise from spectator effects such as $W$ -exchange…

Revisiting radiative decays of $1^{+-}$ heavy quarkonia in the covariant light-front approach

Yan-Liang Shi

We revisit the calculation of the width for the radiative decay of a $1^{+-}$ heavy $Q Q ˉ$ meson via the channel $1^{+-} \to 0^{-+} + γ$ in the covariant light-front quark model…

Dynamical Symmetry Breaking in Chiral Gauge Theories with Direct-Product Gauge Groups

Yan-Liang Shi, Robert Shrock

We analyze patterns of dynamical symmetry breaking in strongly coupled chiral gauge theories with direct-product gauge groups $G$ . If the gauge coupling for a factor group $G_i \su…

The radiative decays of $0^{++}$ and $1^{+-}$ heavy mesons

Hong-Wei Ke, Xue-Qian Li, Yan-Liang Shi

The radiative decay is believed to be an ideal lab to study hadronic structure of newly observed resonances because the reactions are governed by only the electromagnetic interacti…

Is $Z_{b} (10610)$ a Molecular State?

Hong-Wei Ke, Xue-Qian Li, Yan-Liang Shi +2

Whether molecular states indeed exist in nature has been disputed for a long time. Several new resonances have been observed in the recent experiments and they seem to be of exotic…
