EXOTIC HADRONS OF MINIMAL PENTAQUARK $(qqqq{\bar q}) STATES

It is shown that the exotic non-qqq hadrons of pentaquark states can be clearly distinguished from the conventional qqq-baryon resonances or their hybrids if the flavor of is different from any of the other four quarks. We suggest the physical process , which can be investigated at the Thomas Jefferson National Accelerator Facility (JLab), as an ideal process to search for the existence or non-existence of the exotic hadron of minimal pentaquark state .
