摘要：

We study the photoproduction of the K-*(892) vector meson from both the charged and neutral reactions gamma p -> K*+Lambda and gamma n -> K-*0 Lambda. The production mechanisms that we consider include t-channel K-*,K,kappa exchanges, s-channel nucleon diagrams, and u-channel Lambda,Sigma,Sigma(*) diagrams. These could constitute important backgrounds for future investigation of "missing" resonances that can be searched for especially in these reactions. The t-channel K meson exchange is found to dominate both reactions. The total and differential cross sections are presented together with some spin asymmetries.
