Abstract
Recently, the CLAS collaboration at Thomas Jefferson Nation Acceleration Facility reported the total cross section data for K* photoproduction, and found that the t-channel K exchange dominates the production amplitudes at small scattering angles. The measurement of forward-angle beam spin asymmetries for this reaction, where the theoretical calculations show an unambiguous signal, would establish the role of the k(800)W. e have measured the photon beam asymmetry for the γp → K*0∑+ reaction on a Liquid Hydrogen target in the energy from threshold to 3.0 GeV by using a linearly polarized photon beam at Spring-8. Keywords: Beam asymmetry; K* (892) photoproduction; Spring-8/LEPS.
