Inclusion of heavy spin effects in the $ud\bar{b}\bar{b}$ $I(J^P)=0(1^{-})$ four-quark channel in the Born-Oppenheimer approximation

Jakob Hoffmann, André Zimermmane-Santos, Marc Wagner

We refine our previous study of a $ud\bar{b}\bar{b}$ tetraquark resonance with quantum numbers $I(J^P)=0(1^{-})$, which is based on antiheavy-antiheavy lattice QCD potentials,…
