HYPERON-ANTIHYPERON PRODUCTION IN NUCLEON-ANTINUCLEON COLLISIONS AND THE RELATIVE $Sigma$$-$$lambda$ PARITY
A discussion is given of hyperon-antihyperon production in nucleon- antinucleon collisious near threshold. The rate for the reaction and the polarization of the outgoing baryons are calcudated in terms of three amplitudes characterizing the transition operators in the two cases of even and odd relative SIGMA -A parity. In terms of these amplitudes, a correlation function which gives the angular correlations between the pion momenta from the subsequent decay of the hyperon and antihyperon, and the vectors involved in the production process, is given for each relative parity. The possibility of this class of experiments being useful in determining the relative SIGMA /sup 0/- LAMBDA parity, as well as the relattve charged EPSILON - LAMBDA parity, is discussed. (auth)
