    "abstract": "We discuss the stability of multiquark systems within the recent model of\nGlozman et al. where the chromomagnetic hyperfine interaction is replaced by\npseudoscalar-meson exchange. We find that such an interaction binds a heavy\ntetraquark system $QQ\\bar q\\bar q$ ($Q=c, b$ and $q=u, d)$ by $0.2-0.4$ GeV.\nThis is at variance with results of previous models where $cc\\bar q\\bar q$ is\nunstable.",
