Abstract

We discuss the new state DsJ(2317)D_{sJ}(2317) discovered by BaBar and demonstrate using QCD inequalities that if indeed the f0(980)f_0(980) and the new DsJ(2317)D_{sJ}(2317) (0+0^+) are primarilly made of four quarks that a new I=0 ``DˉD\bar DD bound state'' at a mass smaller than 3660 MeV must exist. Observation of such a state will constitute definitive evidence for four-quark states.
