Inspired by the new TOTEM data on elasticppscattering at 13 TeV, we study the possibility to describe all the diffractive collider data (σtot,dσel/dt,ρ≡ReA/ImA,σlowMD) in a wide interval of energy (0.0625 to 13 TeV) in the framework of a two-channel eikonal model. We show that a satisfactory description can be achieved without an odd-signature (Odderon) exchange contribution. We consider the possible role of the QCD Odderon which may improve the description ofρand discuss the importance of the odd-signature term if the amplitude were to exceed the black disc limit.
