Lattice QCD studies of doubly heavy tetraquarks

The existence of bound doubly heavy tetraquark states was confirmed by the recent LHCb discovery of the doubly charmed T_cc, less than 1MeV below the meson pair threshold. Other states with two heavy (bottom or charm) quarks could also be bound, perhaps more deeply. Here we discuss previous lattice QCD work by the group at York, and the developments in our current, updated analysis of various heavy-heavy-light-light tetraquark candidates.

This talk is part of the HEP phenomenology joint Cavendish-DAMTP seminar series.
