Description

We explore the existence of tetraquark resonances with lattice QCD potentials computed for a static b̄b̄ pair in the presence of two light quarks ud. We use the Born-Oppenheimer approximation and an extension of the emergent wave method, where effects of the heavy quark spins are included via the mass difference of the B and the B* meson. Focus is given on a resonance with isospin I = 0 and relative angular momentum L=1 of the heavy quarks b̄b̄.
