Exploring $T_{{\rm Y}{\rm Y}}$ tetraquark candidates in a coupled-channels formalism

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

We investigate the spectrum of $T_{{\rm Y}{\rm Y}}$ tetraquark candidates within a coupled-channels framework. The analysis includes all $L\le 2$ combinations of ${\rm Y}(1S)$, ${\rm Y}(2S)$, ${\eta }_b(1S)$, a…
