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…

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 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…
