N2 - Recent observations by Belle and BESIII of charged quarkonium-like resonances give new stimulus for theoretical investigation of exotic hadrons in general and heavy tetraquarks in particular. We use QED2, a confining theory, as a model for the masses and decays of tetraquarks. Here we discuss the states (QQ̄qq̄) and (QQ̄qq̄) (and its anti-particle), where Q and q are two fermion flavors with masses M and m, so that M >m. Wethendiscussdecaymodesofthesestatesinto (QQ̄), (qq̄), (Qq̄), (Q̄q). Itturns out that (QQ̄qq̄) is stable, while (QQ̄qq̄) is not.
