Abstract 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, we develop the final-state rescattering mechanism to study the

CP violation (CPV) in the baryon sectors has not yet been established experimentally. In this work, we propose to search for the hyperon CPV through the Cabibbo-favored charm-baryon decaying processes involving a hyperon in the final states, such as

Abstract In this work, we calculate the transition form factors of $$\Lambda _b$$ Λ b decaying into proton and $$N^*(1535)$$ N ∗ ( 1535 ) ( $$J^P={1/2}^+$$ J P = 1 / 2 + and $${1/2}^-$$ 1 / 2 - respectively) within the framework of light-cone sum

Abstract Discoveries of tetraquarks not only enrich the hadronic spectrum but also provide more platforms to understand quantum chromodynamics. We study the production processes of hidden-charm and open-charm tetraquarks in B decays by analyzing thei

Abstract The decay width of the $$D_s^{*}$$ D s ∗ meson is dominated by the electromagnetic mode $$D_s^*\rightarrow D_s \gamma $$ D s ∗ → D s γ , and it is thus the longest-lived charged vector meson. In light of this point, we perform the fir

Abstract We reanalyze the $$\Lambda _b\rightarrow p$$ Λ b → p transition form factors in the perturbative QCD (PQCD) approach by including higher-twist light-cone distribution amplitudes (LCDAs) of a $$\Lambda _b$$ Λ b baryon and a proton. The pr

Abstract We propose to search for the open heavy-flavor exotic states with the quark components of $$Qs{\bar{u}}{\bar{d}}$$ Q s u ¯ d ¯ with $$Q=b,c$$ Q = b , c via their weak decays. If there exist such exotic states below the BK or DK thresholds,

Abstract We propose a systematic theoretical framework for the topological amplitudes of the heavy meson decays and their SU(N) decomposition. In the framework, the topologies are expressed in invariant tensors and classified into tree- and penguin-o
