A femtoscopic tale of two -parities: the and the isovector partner of the
Pan-Pan Shi, Miguel Albaladejo, Feng-Kun Guo +1
Understanding the nature of the exotic and states, and searching for the predicted isovector partner of the , remain central challenges…
Low-energy scattering of the and system
Jiang Yan, Xiong-Hui Cao, Meng-Lin Du +1
The paper studies low‑energy interactions between the charmonium state J/ψ and light pseudoscalar mesons (π and K) using dispersion‑relation techniques, extracting scattering lengt…
Effective Range Expansion with the Left-Hand Cut: Higher Order Improvements
Wen-Jia Wang, Bing Wu, Meng-Lin Du +1
A model-independent parameterization of the low-energy scattering amplitude that incorporates the left-hand cut from one-particle exchange, an extension of the conventional effecti…
Determination of the and the states from joint analysis of experimental and lattice data
Yun-Hua Chen, Meng-Lin Du, Feng-Kun Guo
We present a unified analysis of the and states considering both experimental and lattice data. The study simultaneously includes the processes $e^+e^- \…
Extraction of the pion-nucleon coupling constant using the effective-range expansion with the left-hand cut
Bo-Yang Liu, Bing Wu, Ji-Wei Fu +3
We apply the generalized effective-range expansion of Phys. Rev. Lett. 135, 011903(2025), which incorporates the left-hand cut from one-pion exchange, to low-energy neutron-proton…
Deciphering the mechanism of -nucleon scattering
Bing Wu, Xiang-Kun Dong, Meng-Lin Du +2
The low-energy scattering is important for various reasons: it is related to the hidden-charm pentaquark states, provides insights into the role of gluons in nucleon…
