Description
There were no experimental evidence for existence of a hadron with a quark configuration other than three quarks or a quark-antiquark pair although QCD does not forbid the existence of other combination such as qq-bar qq-bar or qqqqq-bar. Since the LEPS at SPring-8 collaboration reported the first evidence for the Θ+ which has a quark configuration of uudds-bar, extensive experimental efforts have been made to confirm the existence of the Θ+. In this paper, the experimental study of the Θ+ at LEPS together with the experimental situation and the future prospect are reported. (author)
