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…

The dynamically generated $N (1535)$ state in the $Λ_{c}^{+} \to p K ˉ^{0} π^{0}$ decay

Ying Li, En Wang, Li-Sheng Geng +1

We present a theoretical analysis of the process $Λ_{c}^{+} \to p K ˉ^{0} π^{0}$ within the chiral unitary approach, with particular emphasis on the dynamically generated $N (1535)$ reso…

Search for the low-lying excited baryon $Σ^{*} (1/ 2^{-})$ through process $Λ_{c}^{+} \to Λ K^{0} π^{+}$

Sheng-Chao Zhang, Wen-Tao Lyu, Guan-Ying Wang +2

Motivated by recent BESIII measurements of the singly Cabibbo-suppressed processes $Λ_{c}^{+} \to Λ K^{+} π^{0}$ and $Λ_{c}^{+} \to Λ K_{S}^{0} π^{+}$ , we investigate the process $Λ_{c}^{+} \to Λ K^{0} π^{+}$ …

Modulus stabilization of modular flavor models in Jordan frame supergravity

Fei Wang, Ying Kai Zhang

We propose to discuss the modular flavor model and the stabilization of single modulus field in the Jordan frame supergravity with non-minimal scalar-curvature coupling of the form…

Finding a clean process $B^{-} \to K^{-} D^{0} K^{0}$ to probe absolutely exotic four-quark states

Man-Yu Duan, Guan-Ying Wang, Yun Liang +3

Motivated by the observations of $T_{c s ˉ 0} (2900)^{0}$ and $T_{c s ˉ 0} (2900)^{++}$ , we propose to search for $\tcsbar^0$ in the cleaner process $B^{-} \to K^{-} D^{0} K^{0}$ . In the $…
