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…
Comparing relativistic and non-relativistic quark pair creation models
Xiu-Li Gao, Yu-Hui Zhou, Bin Wu +1
We investigate the strong decay properties of light unflavored and strange mesons within a relativistic quark-pair-creation (QPC) framework, and compare the results with those obta…
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…
Effective range expansion with a long-range force
Meng-Lin Du, Feng-Kun Guo, Bing Wu
The validity range of the time-honored effective range expansion can be very limited due to the presence of a left-hand cut close to the two-particle threshold. Such a left-hand cu…
The -nucleon interaction mechanism: A theoretical study based on scattering length
Bing Wu, Xiang-Kun Dong, Meng-Lin Du +2
The low-energy scattering is of significant importance for various reasons. It is deeply interconnected with the hidden-charm pentaquark states, provides insights int…
