New physics from TOTEM’s recent measurements of elastic and total cross sections

Abstract: We analyze the recently discovered phenomena in elastic proton-proton scattering at the LHC, challenging the standard Regge-pole theory: the low-|t| "break" (departure from the exponential behavior of the diffraction cone), the accelerating rise with energy of the forward slope 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 T eV ) = 0.1 ± 0.01, and especially its contribution at the dip region, measured recently by TOTEM.… Show more

“…At LHC energies, the pomeron and its C-odd counterpart, the odderon, entirely dominate [34], however, to be consistent with the lower energy data, particularly those from the ISR, we include also two secondary reggeons (f and ω) in the fitting procedure.…”
