Аннотация:We find conditions under which the ratio of particle and antiparticle total scattering cross sections sigma(+)(s)/sigma(-)(s) --> 1 as s --> infinity. If the forward elastic scattering amplitudes become purely real asymptotically, then their ratio tends to -1. We prove that sigma(+)(s)/sigma(-)(s) congruent to 1 for sigma(+)(s) much greater than pi/m(pi)(2), where m(pi) is the pi-meson mass. We show that the asymptotic relations obtained have finite-energy analogues for some processes.
