Abstract

We analyze the recently discovered phenomena in elastic proton-proton scattering at the LHC, challenging the standard Regge-pole theory: the low-t|t| "break" (departure from the exponential behavior of the diffraction cone), the accelerating rise with energy of the forward slope B(s,t=0)B(s,t=0), the absence of secondary dips and bumps on the cone and the role of the odderon in the forward phase of the amplitude, ρ(13 TeV)=0.1±0.01\rho(13~TeV)=0.1\pm0.01, and especially its contribution at the dip region, measured recently by TOTEM. Relative contributions from different components to the scattering amplitude are evaluated from the fitted model.
