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 Mπ+π will be an undoubted signal of odderon existence. To make numeral estimates more definite, we limit ourselves by the region Mπ+π = 1.1 ÷ 1.5 GeV, where in the odderon mechanism of dipion production, the production via single f2(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 f2 photoproduction cross section (without referring to any particular model of the odderon).
