Abstract

We discuss the stability of multiquark systems within the recent model of Glozman et al. where the chromomagnetic hyperfine interaction is replaced by pseudoscalar-meson exchange. We find that such an interaction binds a heavy tetraquark system QQ q q (Q=c, b and q=u, d) by 0.2-0.4 GeV. This is at variance with results of previous models where cc q q is unstable.
