A coupled-channel perspective analysis on bottom-strange molecular pentaquarks

Qing-Fu Song, Qi-Fang Lü, Xiaonu Xiong

At present work, we systematically study various bottom-strange molecular pentaquarks to search for possible bound states and resonances by adopting one-boson-exchange model within…

Triply-heavy tetraquarks in an extended relativized quark model

Qi-Fang Lü, Dian-Yong Chen, Yu-Bing Dong +1

In this paper, we adopt an extended relativized quark model to investigate the triply-heavy tetrquarks systematically. The mass spectra are obtained by solving the four-body relati…

The newly observed $Λ_{b} (6072)^{0}$ structure and its $ρ -$ mode nonstrange partners

Wei Liang, Qi-Fang Lü

Inspired by the newly observed $Λ_{b} (6072)$ structure, we investigate its strong decay behaviors under various assignments within the $^{3} P_{0}$ model. Compared with the mass and total…

Canonical interpretations of the newly observed $Ξ_{c} (2923)^{0}$ , $Ξ_{c} (2939)^{0}$ and $Ξ_{c} (2965)^{0}$ resonances

Qi-Fang Lü

Three neutral resonances $Ξ_{c} (2923)^{0}$ , $Ξ_{c} (2939)^{0}$ and $Ξ_{c} (2965)^{0}$ have been observed in the $Λ_{c}^{+} K^{-}$ mass spectrum by the LHCb Collaboration. Given the $Ξ_{c}$ and $Ξ_c^\pri…

Strong decays of the newly observed narrow $Ω_{b}$ structures

Wei Liang, Qi-Fang Lü

Motivated by the newly observed narrow structures $Ω_{b} (6316)^{-}$ , $Ω_{b} (6330)^{-}$ , $Ω_{b} (6340)^{-}$ , and $Ω_{b} (6350)^{-}$ in the $Ξ_{b}^{0} K^{-}$ mass spectrum, we investigate the strong decays…

Strong decays of the higher excited $Λ_{Q}$ and $Σ_{Q}$ baryons

Qi-Fang Lü, Xian-Hui Zhong

In this work, we preform a systematic study of the strong decays for the higher singly heavy baryon resonances $Λ_{Q} (3 S)$ , $Λ_{Q} (2 P)$ , $Λ_{Q} (2 D)$ , $Λ_{Q} (1 F)$ , $Σ_{Q} (3 S)$ , $Σ_{Q} (2 P)$ , $Σ_…

Interpretation of the newly observed $Λ_{b} (6146)^{0}$ and $Λ_{b} (6152)^{0}$ states in a chiral quark model

Kai-Lei Wang, Qi-Fang Lü, Xian-Hui Zhong

The strong decays of the low-lying $λ$ -mode $Λ_{b} (1 D, 2 S)$ and $Σ_{b} (2 S)$ states are studied in a chiral quark model. We find that: (i) the newly observed $Λ_{b} (6146/6152)$ resonances…

Canonical interpretation of the newly observed $Λ_{b} (6146)^{0}$ and $Λ_{b} (6152)^{0}$ via strong decay behaviors

Wei Liang, Qi-Fang Lü, Xian-Hui Zhong

Stimulated by the newly observed $Λ_{b} (6146)^{0}$ and $Λ_{b} (6152)^{0}$ resonances, we investigate the strong decays of the low-lying singly bottom baryons within the quark pair creation…

Strong decay of $Λ_{c} (2940)$ as a $2 P$ state in the $Λ_{c}$ family

Qi-Fang Lü, Li-Ye Xiao, Zuo-Yun Wang +1

Considering the mass, parity and $D^{0} p$ decay mode, we tentatively assign the $Λ_{c} (2940)$ as the $P -$ wave states with one radial excitation. Then, via studying the strong decay be…

A new decay mode of higher charmonium

Li-Ye Xiao, Xin-Zhen Weng, Qi-Fang Lü +2

We calculate the $Λ_{c} Λ ˉ_{c}$ partial decay width of the excited vector charmonium states around 4.6 GeV with the quark pair creation model. We find that the partial decay width of…

Regge-like relation and a universal description of heavy-light systems

Kan Chen, Yubing Dong, Xiang Liu +2

Using the Regge-like formula $(M - m_{Q})^{2} = π σ L$ between hadron mass $M$ and angular momentum $L$ with a heavy quark mass $m_{Q}$ and a string tension $σ$ , we analyze all the heavy-light…
