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.
Experiments of this kind are presently performed at BESIII where many physicists of our division are participating. Therefore the presentation aims to be as clear and complete as possible.
