Abstract

We analyze the masses of the doubly-heavy tetraquark states TQQ using the variational method. We also find that our full model calculations give, in general, smaller binding energy, compared to those from the simplified quark model that treats quark dynamics inside the tetraquark the same as that inside a baryon. We investigate the main origin of this weaker binding energy. The original work is described in W. Park, S. Noh, S.H. Lee, Nucl. Phys. A 983, 1 (2019).
