Recently, LEPS collaboration reported the parity spin asymmetry for the γ p → K* 0Σ+ reaction using linearly polarized photons at beam energies from 1.85 to 2.96 GeV. The parity spin asymmetry (Pσ = 2ρ1 1-1 - ρ1 00) was obtained, with large positive asymmetry at forward angles. This supports that natural-parity exchange is dominant at forward angles for K* 0Σ+ photoproduction, which is consistent with κ meson-exchange. The differential cross sections for the γ p → K* 0Σ+ reaction are presented at forward angles averaged over all beam energies. There is good agreement with the differential cross sections from the CLAS and the CBELSA/TAPS collaborations.
