Lattice QCD investigation of a doubly-bottom $\bar{b}\bar{b}ud$ tetraquark with quantum numbers $I(J^P)=0(1^{+})$

Luka Leskovec, Stefan Meinel, Martin Pflaumer +1

We use lattice QCD to investigate the spectrum of the $\bar{b}\bar{b}ud$ four-quark system with quantum numbers $I(J^P)=0(1^{+})$. We use five different gauge-link ensembles wit…
