Saša Prelovšek: Evidence for a doubly charm tetraquark pole from lattice QCD

Recently LHCb collaboration discovered a doubly charmed tetraquark (Tcc) with exotic flavor content ccud slightly below DD threshold. I'll present the first lattice QCD determination of DD scattering amplitude which is needed to theoretically establish Tcc. The resulting scattering amplitude provides a signature for a pole related to Tcc for the first time with ab-initio methods.
