Abstract

An exotic S = +1 baryon was observed in exclusive photoproduction from the deuteron. The peak was at 1.542±0.005 GeV/c2 with a measured width of 0.021 GeV/c2 FWHM, which is largely determined by experimental mass resolution. Photon beams were produced by 2.474 and 3.115 GeV electrons incident on a bremsstrahlung radiator of thickness 10-4 radiation lengths. The mass and width of the observed peak were found to be consistent with a narrow S = +1 baryon by other experimental groups.

N2 - An exotic S = +1 baryon was observed in exclusive photoproduction from the deuteron. The peak was at 1.542±0.005 GeV/c2 with a measured width of 0.021 GeV/c2 FWHM, which is largely determined by experimental mass resolution. Photon beams were produced by 2.474 and 3.115 GeV electrons incident on a bremsstrahlung radiator of thickness 10-4 radiation lengths. The mass and width of the observed peak were found to be consistent with a narrow S = +1 baryon by other experimental groups.
