Description

We investigate four-quark systems consisting of two heavy anti-bottom quarks and two light up/down quarks. To this end we solve a coupled Schrödinger equation for the anti-bottom-anti-bottom separation using potentials computed via lattice QCD in the limit of static anti-bottom quarks. This coupled Schrödinger equation allows to incoporate effects due to the heavy anti-bottom spins.
