Abstract We investigate the weak decays of the triply heavy baryon $$\Omega _{QQQ}$$ Ω QQQ in the light-front quark model. Since $$\Omega _{QQQ}$$ Ω QQQ consists of three indistinguishable identical heavy quarks, the commonly adopted quark–diquar

Abstract The measurements on a few pentaquarks states $$P_c(4440)$$ P c ( 4440 ) , $$P_c(4457)$$ P c ( 4457 ) and $$P_{cs}(4459)$$ P cs ( 4459 ) excite our new interests about their structures. Since the masses of $$P_c(4440)$$ P c ( 4440 ) and $$P_c

Abstract In this work, we study the weak decay between two heavy baryons $${\mathcal {B}}_i(\frac{1}{2}^+)\rightarrow {\mathcal {B}}_f(\frac{3}{2}^+)$$ B i ( 1 2 + ) → B f ( 3 2 + ) in the light-front quark model where three-quark picture is employ

Abstract In this work, we propose to search for the exotic doubly charmed meson $$T_{cc}^+$$ T cc + and its analog $$T_{cc\bar{s}}^+$$ T c c s ¯ + in $$B_c^+$$ B c + decays, which provide a good environment for the formation of the exotic state cont

Abstract We investigate the process $$B\rightarrow \bar{D}D_s \pi $$ B → D ¯ D s π via several rescattering processes. It is shown that the triangle singularity (TS) peak around the $$D^*K^*$$ D ∗ K ∗ threshold generated from the $$\chi _{c1}

Abstract Recently the LHCb collaboration reported a new exotic state $$T^+_{cc}$$ T cc + which possesses $$cc\bar{u}\bar{d}$$ c c u ¯ d ¯ flavor structure. Since its mass is very close to the threshold of $$D^0D^{*+}$$ D 0 D ∗ + (or $$D^{*0}D^{+}

Abstract We investigate the $$B^+\rightarrow J/\psi \phi K^+$$ B + → J / ψ ϕ K + decay via various rescattering diagrams. Without introducing genuine exotic resonances, it is shown that the $$Z_{cs}(4000)$$ Z cs ( 4000 ) , $$Z_{cs}(4220)$$ Z cs (

Abstract Recently LHCb declared a new structure X(6900) in the final state di- $$J/\psi $$ J / ψ which is popularly regarded as a cc- $$\bar{c}\bar{c}$$ c ¯ c ¯ tetraquark state. Within the Bethe–Salpeter (B–S) framework we study the possible

Abstract The LHCb collaboration recently reported the observation of a narrow peak in the $$D^- K^+$$ D - K + invariant mass distributions from the $$B^+\rightarrow D^+ D^- K^+$$ B + → D + D - K + decay. The peak is parameterized in terms of two re

Abstract In this work we study the weak decays of $$\Xi _{cc}\rightarrow \Xi _c$$ Ξcc→Ξc and $$\Xi _{cc}\rightarrow \Xi '_c$$ Ξcc→Ξc′ in the light-front quark model. Generally, a naive, but reasonable conjecture suggests that the cc subsyst
