Thermal width shift of $Δ^{++}$ in a pion gas

Ying Zhang, Peng-Yu Niu, Xin-yue Hu +2

We compute the thermal width shift of the $Δ^{++}$ resonance induced by a pion gas within a nonrelativistic effective field theory framework. The $Δ^{++}$ self-energy is evaluated…

Revisit the diquark of $Λ_{c}$ in the $Λ_{c} \to Λ K^{+}$ and $Λ_{c} \to Σ^{0} K^{+}$ processes

Peng-Yu Niu, Qian Wang, Qiang Zhao

The spatial distributions of $[u d]$ diquark and heavy-light diquark of the SU(3)-flavor antitriplet charmed baryons are investigated by the two singly Cabibbo-suppressed hadronic w…

Resonance parameters of the vector charmoniumlike state $G (3900)$

Quanxing Ye, Zhenyu Zhang, Meng-Lin Du +3

Motivated by the updated analysis of the $G (3900)$ by the BESIII collaboration, we perform a global analysis of the cross sections of the $e^{+} e^{-} \to D D ˉ$ , $e^+e^-\to D\bar{D}^…

The Cabibbo-favored hadronic weak decays of the $Ξ_{c}$ in the quark model

Peng-Yu Niu, Qian Wang, Qiang Zhao

The Cabibbo-favored hadronic weak decay of the $Ξ_{c}^{+} \to Ξ^{0} π^{+}$ , $Ξ_{c}^{0} \to Ξ^{-} π^{+}$ , $Ξ_{c}^{0} \to Ξ^{0} π^{0}$ , $Ξ_{c}^{0} \to Ξ^{0} η^{(^{'})}$ and $Ξ_{c}^{0} \to Ξ^{+} K^{-}$ are studied in the non-relativis…

Production of exotic hadrons in $pp$ and nuclear collisions

Jinhui Chen, Feng-Kun Guo, Yu-Gang Ma +5

Exotic hadrons beyond the conventional quark model have been discovered in the past two decades. Investigations of these states can lead to deep understanding of nonperturbative dy…

The pole structures of the $X (1840) / X (1835)$ and the $X (1880)$

Peng-Yu Niu, Zhen-Yu Zhang, Yi-Yao Li +2

Whether the $N N ˉ$ interaction could form a state or not is a long standing question, even before the observation of the $p p ˉ$ threshold enhancement in 2003. The recent hi…

Theoretical study on the contributions of $ω$ meson to the $X (3872) \to J / ψ π^{+} π^{-}$ and $J / ψ π^{+} π^{-} π^{0}$ decays

Hao-Nan Wang, Qian Wang, Ju-Jun Xie

With the newly measurements of $X (3872) \to J / ψ π^{+} π^{-}$ from LHCb Collaboration, in addition to the dominant contribution from the $ρ^{0}$ meson, we perform a theoretical study on the…

Hyperon Weak Radiative Decay

Peng-Yu Niu, Jean-Marc Richard, Qian Wang +1

We revisit the hyperon weak radiative decays in the framework of the non-relativistic constituent quark model. This study confirms the nonlocal feature of the hyperon weak radiativ…
