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…

Why is the $Z_{c} (3900)$ absent in the $h_{c} π$ 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…
