Bottomonium resonances from lattice QCD static-static-light-light potentials
Abstract
We study I=0 quarkonium resonances decaying into pairs of heavy-light mesons using static-static-light-light potentials from lattice QCD. To this end, we solve a coupled channel Schr\"odinger equation with a confined quarkonium channel and channels with a heavy-light meson pair to compute phase shifts and T matrix poles for the lightest decay channel. We discuss our results for S, P, D and F wave states in the context of corresponding experimental results, in particular for (10753) and (10860).
