摘要：

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