Seminarium: Production of Lambda-Lambdabar pairs in e+e- annihilation
The seminar describes how one calculates the cross-section distribution for e+e- annihilation into Lambda-Lambdabar pairs. The reaction is assumed to proceed via vector-meson intermediate states, exemplified by the photon and the J/Psi meson. The hyperons are detected indirectly through their N-pi weak decays.
