Decay coupling constant sum rules for tetraquarks $\mathbf{T}[(\bar{\mathbf{Q}}\mathbf{q})(\mathbf{Q}\bar{\mathbf{q}})]$ with broken SU(3) symmetry

Abstract

For tetraquarks of the form $T[(\bar{Q}q)(Q\bar{q})]$ we give sum rules for their decay coupling constants, taking into account the SU(3) symmetry breaking interactions to first order.
