Role of $a_{0} (1710)$ in the $J / ψ \to ρ^{+} ρ^{-} ω$ and $J / ψ \to γ ρ^{0} ω$ reactions

Wen-Tao Lyu, Luis Roca, Eulogio Oset

We investigate the strong decay $J / ψ \to ρ^{+} ρ^{-} ω$ and the radiative decay $J / ψ \to γ ρ^{0} ω$ , taking into account the $S$ -wave $K^{*} K ˉ^{*}$ , $ρ ω$ and $ρϕ$ final-state interactions, whic…

Role of $Ξ (1690)$ in the $J / ψ \to Ξ^{0} Λ ˉ K^{0}$ reaction

Wen-Tao Lyu, Lian-Rong Dai, Eulogio Oset

Motivated by the recent BESIII measurements of the $J / ψ \to Ξ^{0} Λ ˉ K_{S}^{0} + c . c .$ process, we investigate this reaction by considering the contributions from the $Ξ (1690)$ , $Λ(1890…

Exotic hadrons associated with $b$ -quark

Xinchen Dai, Sen Jia, Alexey Nefediev +3

Compared to charmonium-like states, exotic hadrons associated with $b$ -quark offer distinct advantages for exploring the nature of multiquark phenomena and the dynamics of the stro…

Probing the isospin structure and low-lying resonances in $Λ_{c}^{+} \to n K ˉ^{0} π^{+}$ decays

Meng-Yuan Li, Guan-Ying Wang, Neng-Chang Wei +2

The Cabibbo-favored decay $Λ_{c}^{+} \to n K ˉ^{0} π^{+}$ offers a unique window to explore unresolved puzzles in the low-energy baryon spectroscopy and the isospin dynamics of the $\ba…

Searching for a $P_{cs} (4200)$ state in the $Λ_{b} \to ϕ η_{c} Λ$ reaction

Wen-Tao Lyu, Eulogio Oset

We propose the $Λ_{b} \to ϕ η_{c} Λ$ reaction to observe a $P_{cs}$ state around $4200$ MeV, predicted at lower masses than expected from comparison with the $P_{c}$ states, stemming as a c…

Effective Field Theory Description of Light Dilaton

Qing-Hong Cao, Jian-Nan Ding, Bing-Hui Ge +2

Dilatons, the CP-even pseudo-Nambu-Goldstone bosons arising from spontaneous scale symmetry breaking, offer a compelling alternative to axion-like particles (ALPs) yet lack a compr…
