Fayyazuddin,

Photoproduction of K mesons is considered at low energy so that only s and p waves are important. The contribution of Born terms, K* meson, and N* resonance is calculated for the reaction gamma + N -- K + Y. The values of unknown parameters such as hyperon magnetic moments and relative strengths and signs of g/sub kN LAMBDA /, g/sub Kn SIGMA /, G/sub K*N LAMBDA / an d g/sub K*N SIGMA / coupling constants as given by the octet model of unitary symmetry, are used. A reasonable fit to the experimental data on angular distributions for the reactions gamma + p yields K/sup +/ + LAMBDA /sup 0/ and gamma + p yields K/sup +/ + SIGMA /sup 0/ is obtained in this model. In the model odd K LAMBDA and even LAMBDA SIGMA parities are implied. Thus the difference in the angular distribution of K/sup +/ LAMBDA /sup 0/ and K/sup +/ SIGMA /sup 0/ production can be explained for even LAMBDA SIGMA parity. Certain predictions for other reactions were obtained that can be tested experimentally when the data on these reactions will be avatlable. (auth)
