Two-body exit channels in p¯-p and p¯-nucleus annihilations

Abstract
Our previous model is used and improved to estimate branching ratios for B=0 (N¯N) and B=1 (N¯NN) annihilations. Particular emphasis is put on the two-body exit channels. It is pointed out that relative values of two-body exit channel branching ratios in B=1 annihilations are largely model independent. Nuclear effects in p¯-nucleus annihilation at rest are estimated.
