Bootstrapping Two-Nucleon Effective Field Theories

Q. N. Micha-Mba, M. S. Sánchez, P. G. Ortega +2

Chiral EFT yields singular potentials that require regularization and renormalization when implemented in a dynamical equation such as the Lippmann--Schwinger equation. We employ t…

Exploring $T_{ΥΥ}$ tetraquark candidates in a coupled-channels formalism

P. G. Ortega, D. R. Entem, F. Fernandez +1

We investigate the spectrum of $T_{ΥΥ}$ tetraquark candidates within a coupled-channels framework. The analysis includes all $L \leq 2$ combinations of $Υ (1 S)$ , $Υ (2 S)$ , $η_{b} (1 S)$ , a…
