Weak decays of the triply heavy baryons in the three-quark picture with the light-front quark model

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

We investigate the weak decays of the triply heavy baryon $Ω_{QQQ}$ in the light-front quark model. Since $Ω_{QQQ}$ consists of three indistinguishable identical heavy quarks, the…

Study on the possible molecular states composed of $Λ_{c} D ˉ^{}$ , $Σ_{c} D ˉ^{}$ , $Ξ_{c} D ˉ^{}$ and $Ξ_{c}^{'} D ˉ^{}$ in the Bethe-Salpeter frame based on the pentaquark states $P_{c} (4440)$ , $P_{c} (4457)$ and $P_{cs} (4459)$

Hong-Wei Ke, Fang Lu, Hai Pang +2

The measurements on a few pentaquarks states $P_{c} (4440)$ , $P_{c} (4457)$ and $P_{cs} (4459)$ excite our new interests about their structures. Since the masses of $P_{c} (4440)$ and $P_c(4…

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…

Searching for doubly charmed tetraquark candidates $T_{cc}$ and $T_{cc s ˉ}$ in $B_{c}$ decays

Yuan Li, Ying-Bo He, Xiao-Hai Liu +2

In this work, we propose to search for the exotic doubly charmed meson $T_{cc}^{+}$ and its analog $T_{cc s ˉ}^{+}$ in $B_{c}^{+}$ decays, which provide a good environment for the forma…

Possible molecular states of $D ˉ^{} K^{}$ ( $D^{} K^{}$ ) and the new exotic states $X_{0} (2900)$ and $X_{1} (2900)$ ( $T_{cs 0}^{a} (2900)^{0}$ and $T_{cs 0}^{a} (2900)^{++}$ )

Hong-Wei Ke, Yi-Fan Shi, Xiao-Hai Liu +1

Two iso-singlet hadron states $X_{0} (2900)$ and $X_{1} (2900)$ with $J = 0$ and 1 respectively, discovered by the LHCb collaboration in 2020, were identified as molecular bound states of…

Triangle singularity in $B^{0} \to π^{-} K^{+} X (3872)$ via the $D_{s 1} D ˉ D^{*}$ loop and possible precise measurement of the $X (3872)$ mass

Mao-Jun Yan, Ying-Hui Ge, Xiao-Hai Liu

We investigate the $B^{0} \to π^{-} K^{+} X (3872)$ decay via the $D_{s 1} (2536) D ˉ D^{*}$ rescattering diagram. The line shape of the $K^{+} X (3872)$ distribution curve around $D_{s1}(2536)…

Possible Molecular States of $D^{()} D^{()}$ and $B^{()} B^{()}$ within the Bethe-Salpeter framework

Hong-Wei Ke, Xiao-Hai Liu, Xue-Qian Li

Recently the LHCb collaboration reported a new exotic state $T_{cc}^{+}$ which possesses $cc u ˉ d ˉ$ flavor structure. Since its mass is very close to the threshold of $D^0D^{*+…

$B^{()} B ˉ^{()}$ intermediate state contribution to $Υ (4 S, 5 S) \to η_{b} + γ$ radiative decay

Hong-Wei Ke, Xue-Qian Li, Xiang Liu

In this work, we investigate the re-scattering effects in the radiative decay $Υ (5 S) \to η_{b} + γ$ , which were suggested to be crucially important for understanding the anomalous largen…
