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…

Effective range expansion with the left-hand cut and its application to the $T_{cc} (3875)$

Meng-Lin Du, Feng-Kun Guo, Bing Wu

The validity range of the widely used traditional effective range expansion can be severely limited by the presence of a left-hand cut near the two-particle threshold. Such a left-…
