Cross section theorem

Pomeranchuk's theorem, named after Soviet physicist Isaak Pomeranchuk, states that difference of cross sections of interactions of elementary particles κ 1 + κ 2 {\displaystyle \kappa _{1}+\kappa _{2}} and κ 1 + κ 2 ¯ {\displaystyle \kappa _{1}+{\bar {\kappa _{2}}}} (i. e. particle κ 1 {\displaystyle {\kappa _{1}}} with particle κ 2 {\displaystyle \kappa _{2}} , and with its antiparticle κ 2 ¯ {\displaystyle {\bar {\kappa _{2}}}} ) approach 0 when s {\displaystyle s\to \infty } , where s {\displaystyle s} is the energy in center of mass system.
