CERTAIN IMPLICATIONS FOR HIGH-ENERGY TOTAL CROSS SECTIONS FROM MULTIPERIPHERAL MODEL

The multiperipheral model is used to relate the experimental fact, σNN̄tot>σNNtot, to the possibility that the NN̄ channel can annihilate into purely meson final states by exchange of N or N̄ trajectories, whereas the NN channel cannot do so. Our argument shows that from the multi-Regge bootstrap point of view, the combination of baryon and antibaryon trajectories will generate a pair of exchange-degenerate trajectories P′ and ω. The same line of reasoning can easily be generalized to include strange particles, as well as the (K-N,K+N) and (π-p,π+p) systems. © 1969 The American Physical Society.
