Inspired by the new TOTEM data on elastic pp scattering at 13 TeV, we study the possibility to describe all the diffractive collider data (sigma(tot), d sigma(el)/dt, rho equivalent to ReA/ImA, sigma(D)(lowM)) 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 of rho and discuss the importance of the odd-signature term if the amplitude were to exceed the black disc limit.
