Semileptonic Decay of $Λ_{b} \to N (1520) ℓ^{-} ν ˉ_{ℓ}$ from QCD Light-cone Sum Rules

Ke-Sheng Huang, Ao-Sheng Xiong, Hua-Yu Jiang +1

We investigate the complete set of vector and axial-vector form factors for the charged-current transition $Λ_{b}^{0} \to N (1520)^{+}$ using QCD light-cone sum rules (LCSRs) based on the…

Branching fraction of $I^_{b c}^{+} \to I^_{c}^{+} J / I ¨ $ in the final-state-interaction approach

Xiao-Hui Hu, Cai-Ping Jia, Ye Xing +1

The process of $I^_{b c}^{+} \to I^_{c}^{+} J / I ¨ $ is among the most favored modes for searching for bottom-charm baryons. However, its branching fraction has never been studied in the…

Final-state rescattering mechanism of double-charm baryon decays: $B_{cc} \to B_{c} P$

Xiao-Hui Hu, Cai-Ping Jia, Ye Xing +1

In this study, we examine the non-leptonic weak decays of doubly charmed baryons, denoted as $B_{cc} \to B_{c} P$ , where $B_{cc}$ represents the doubly charmed ba…

Transition form factors of the $I^_{b} \to I^ (1520)$ in QCD light-cone sum rules

Ke-Sheng Huang, Hua-Yu Jiang, Fu-Sheng Yu

In this work, we investigate the transition form factors for $I^_{b} \to I^ (1520)$ within the framework of light-cone sum rules (LCSR), using the light-cone distribution ampl…

Final-state rescattering mechanism of charmed baryon decays

Cai-Ping Jia, Hua-Yu Jiang, Jian-Peng Wang +1

The dynamical studies on the non-leptonic weak decays of charmed baryons are always challenging, due to the large non-perturbative contributions at the charm scale. In this work, w…
