A NOTE ON THE SIGNS OF THE K$sup +-$-p INTERACTIONS
The signs of the K/sup plus or minus /-p interactions are studied using the Yukawa interaction hamiltonian and varying the type of the (N LAMBDA K) and (N SIGMA K) couplings from scalar to pseudoscalar in the Bonn approximation. The question of whether or not the signs are changed by kigher order effects is explored with emphasis on the 4th order perturbation pion correction. The results for scalar couplings give repulsion for K/sup -/-p and attraction for K/ sup +/-p, and it is concluded that models with scalar couplings give wrong signs for both interactions. For pseudoscalar couplings, the Born term in the Low equation is replaced by an effective scattering interaction, and the pion correction is shown to be small for K/sup +/-p but fairly large and attractive for K/sup -/-p, which is as expected.
