take an interaction consistent with heavy quark spin symmetry, with the dynamical input …

[HTML][HTML] Lowest-lying 12− and 32− ΛQ resonances: From the strange to the bottom sectors

Prediction of new states of and molecular nature

LR Dai, R Molina, E Oset - Physical Review D, 2022 - APS
We extend the theoretical framework used to describe the T cc state as a molecular state of
D* D and make predictions for the D* D* and D s* D* systems, finding that they lead to …

Couplings in coupled channels versus wave functions: Application to the resonance

D Gamermann, J Nieves, E Oset, ER Arriola - Physical Review D—Particles …, 2010 - APS
We perform an analytical study of the scattering matrix and bound states in problems with
many physical coupled channels. We establish the relationship of the couplings of the states …
