As early as in 1970 there were debates [2] that certain particle- antiparticle cross section differences might not vanish with energy growth, and properties of amplitudes not satisfying the conditions of the Pomeranchuk theo- rem have been investigated to much detail by Gribov et al. [3]. Later on, the term odderon, O has been coined [4] for the singularity with C = −1 and the intercept + − α ≈ 1. Because the particle-antiparticle...

Abstract

The interference between the Pomeron and possible odderon mechanisms of diffractive π+π− photoproduction results in charge asymmetry of the produced pions. The observation of charge asymmetry of pions at moderate M π + π − will be an undoubted signal of odderon existence. To make numeral estimates more definite, we limit ourselves by the region M π + π − = 1.1 ÷ 1.5 GeV, where in the odderon mechanism of dipion production, the production via single f 2(1270) resonance is expected to be dominant. We find a very statistically significant effect of the odderon induced charge asymmetry even with very modest estimates for the f 2 photoproduction cross section (without referring to any particular model of the odderon).
