EXOTIC HADRONS OF MINIMAL PENTAQUARK $(qqqq{\bar q}) STATES
EXOTIC HADRONS OF MINIMAL PENTAQUARK $(qqqq{\bar q}) STATES
It is shown that the exotic non-qqq hadrons of pentaquark [Formula: see text] states can be clearly distinguished from the conventional qqq-baryon resonances or their hybrids if the flavor of [Formula: see text] is different from any of the other four quarks. We suggest the physical process [Formula: see text], …
