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…

Resolving the CP Asymmetry Puzzle in $B$ Decays with Unitarized Final-State Interactions

Xin-Yue Hu, Pengyu Niu, Qian Wang +1

A reliable description of direct CP asymmetries in hadronic $B$ decays, among the most sensitive probes of the CKM mechanism and of physics beyond the Standard Model, remains unres…

Three-body final state interactions in $B^{+} \to D D ˉ K^{+}$ decays

Xin-Yue Hu, Jiahao He, Pengyu Niu +2

This paper presents a detailed analysis of the three-body final state interactions in the $B^{+} \to D D ˉ K^{+}$ process, whose phase space is sufficient small. To precisely extract…

Why is the $Z_{c} (3900)$ absent in the $h_{c} I ¨ $ final state?

Quanxing Ye, Ying Zhang, Peng-Yu Niu +1

In this work, we perform a comprehensive phenomenological analysis of the exotic hadronic states $Z_{c} (3900)$ , $Z_{c} (4020)$ , $Z_{b} (10610)$ and $Z_{b} (10650)$ within the framework of Hea…

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}^…

Revisit the diquark of $I^_{c}$ in the $I^_{c} \to I^ K^{+}$ and $I^_{c} \to I^£^{0} K^{+}$ 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…
