Title: Lattice QCD investigation of a doubly-bottom b ¯ b ¯ u d tetraquark with quantum numbers I ( J P ) = 0 ( 1 + )

Abstract

We use lattice QCD to investigate the spectrum of the $$\bar{b} \bar{b} u d$$ four-quark system with quantum numbers $I(J^P) = 0(1^+)$. We use five different gauge-link ensembles with $2+1$ flavors of domain-wall fermions, including one at the physical pion mass, and treat the heavy $$\bar{b}$$ quark within the framework of lattice nonrelativistic QCD. Our work improves upon previous similar computations by considering in addition to local four-quark interpolators also nonlocal two-meson interpolators and by performing a L\"uscher analysis to extrapolate our results to infinite volume. We obtain a binding energy of $$(-128 \pm 24 \pm 10) \, \textrm{MeV}$$, corresponding to the mass $$(10476 \pm 24 \pm 10) \, \textrm{MeV}$$, which confirms the existence of a $$\bar{b} \bar{b} u d$$ tetraquark that is stable with respect to the strong and electromagnetic interactions.
