摘要：
The LEPS experiment at SPring-8 has collected data in the reactions of 1.5-2.4 GeV photons with a liquid deuterium target. The pentaquark baryon circle minus(+) was searched for in the missing mass spectrum of K- and proton from the deuteron. Preliminary results show a peak structure at 1.53 GeV/c(2) above the background spectra which were estimated by two complementary methods. Further confirmations of the circle minus(+) are planned at the current beamline with higher intensity and the newly proposed facilities.
