Description
We investigate p-barp annihilation into B-barB' (where B and B' represent baryons) via q-barq annihilation into Q-barQ (where q and Q represent quarks). Specifying the q-barq (or q-barQ) annihilation spin structure determines the ratios of all polarized amplitudes with B,B' from the 56 under SU(6). We propose to parametrize q-barq→Q-barQ by intermediate gluon and meson states. The model with q-barq→one gluon→Q-barQ with Q = s is worked out in detail. With the exception of p-barp→Sigma-bar-Σ/sup asterisk+/+charge conjugate, it compares favorably with experiment
