Abstract

In the present paper, we extend the Froissaron-Maximal Odderon (FMO) approach at tt different from 0. Our extended FMO approach gives an excellent description of the 3266 experimental points considered in a wide range of energies and momentum transferred. We show that the very interesting TOTEM results for proton-proton differential cross-section in the range 2.76-13 TeV, together with the Tevatron data for antiproton-proton at 1.8 and 1.96 TeV give further experimental evidence for the existence of the Odderon. One spectacular theoretical result is the fact that the difference in the dip-bump region between pˉp\bar pp and pppp differential cross-sections is diminishing with increasing energies and for very high energies (say 100 TeV), the difference between pˉp\bar pp and pppp in the dip-bump region is changing its sign: pppp becomes bigger than pˉp\bar pp at t|t| about 1 GeV2^2. This is a typical Odderon effect. Another important - phenomenological - result of our approach is that the slope in pppp scattering has different behavior in tt than the slope in pˉp\bar pp scattering. This is also a clear Odderon effect.
