In hadron physics, molecular-like multihadron states can interact with compact multiquark states. The latter are modeled as bare in the Hilbert space of a potential model. this work, we study several models relevant to state, and solve their inverse scattering problems. first model, called ``cc,'' is separable We show that it approximate (single-channel short-range) $S$-wave near-threshold phys...

This paper proposes a neural network approach for solving two classical problems in the two-dimensional inverse wave scattering: far field pattern problem and seismic imaging. The mathematical of scattering is to recover scatterer medium based on boundary measurement scattered from medium, which high-dimensional nonlinear. For under circular experimental setup, perturbative analysis shows that ...
