Abstract
A lattice QCD computation close to the physical point finds a near-threshold virtual state in the $D\phantom{\rule{0}{0ex}}{D}^{*}$ scattering channel, that suggests the formation of a loosely bound state at the physical point consistent with the experimental observation of a doubly charmed tetraquark ${T}_{c\phantom{\rule{0}{0ex}}c}^{+}$.
