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 contributions. We find that such an interaction binds a heavy tetraquark systems ( by 0.2-0.4 GeV. This is at variance with results of previous models where is unstable.
