FINAL STATE SCATTERING
Increasing evidence suggests the importance of interactions among the final particles in various production processes. The final state interactions may or may not be strong, and in general take place among all the pairs. Watson's (Phys. Rev. 88: 1163(1952)) theorem is generalized by perturbation theory based on total potentials'' to deal with such situations. A parrameter c approximately 1 is found in this way, which characterizes the amount'' of final state scattering and which theoretically is a measure of the importance of the virtual processes in relation to the physical process. The result is applied to K plus or minus decay and two classes of solutions are found on the assumption of S-wave production of the pions: a/sub 2/ approximately 1.5, a/sub 0/ approximately -0.5; and a/sub 2/ approximately O, a/su b 0/ approximately -0.5, where the a are scattering lengths in the lengths in the isospin states T = 0 and T = 2.
