Roles of $a_{0} (980)^{+} f_{0} (500, 980)$ and $a_{1} (1260)^{+} I^\cdot$ production mechanisms in decay $D_{s}^{+} \to I ¨ ^{+} I ¨ ^{0} I ¨ ^{0} I^\cdot$

Jun He, JUn He

The paper studies the decay D_s^+ → π^+ π^0 π^0 η using a chiral unitary approach, examining how scalar resonances a0(980), f0(500), f0(980) and the axial‑vector a1(1260) contribut…

Virtual state and two-pole structure: $I^ (1690)$ and $I^ (1820)$ from BESIII data on $I ¨ (3686) \to K^{-} I^ I^ˉ ^{+}$

Jun He

We investigate the nature of the $I^ (1690)$ and $I^ (1820)$ resonances by analyzing the recent BESIII data on $I ¨ (3686) \to K^{-} I^ I^ˉ ^{+}$ within a coupled-channel rescattering fram…

Role of $I^£^{*} (1/ 2^{-})$ baryons in $I^_{c} \to I^ I ¨ ^{+} I ¨ ^{+} I ¨ ^{-}$ decay

Jun He

Based on Belle data, the structure around 1435 MeV and the role of the $I^£ (1380)$ resonance in the decay process $I^_{c} \to I^ I ¨ ^{-} I ¨ ^{+} I ¨ ^{+}$ are investigated. The $I^ I ¨ ^{\pm}$ invari…

Productions of bottom and bottom-strange mesons in pion and kaon induced reactions

Jing Liu, Quan-Yun Guo, Qi Wu +2

In the present work, we propose to explore the productions of the bottom and bottom-strange mesons in the high-energy pion and kaon-induced reactions on a proton target. The cross…
