Lack of evidence for an odderon at small t

It is fundamental that the phase of an elastic scattering amplitude is related to its energy variation. We repeat a previous fit to pp and p (p) over bar elastic scattering data from 13 to 13000 GeV, taking better account of the very high accuracy of the 13 TeV data. The conclusion remains that there is no evidence for the existence of an odderon in the small-t data. (C) 2022 The Author(s). Published by Elsevier B.V.

Automated summary

It is found that the phase of an elastic scattering amplitude is closely related to its energy variation. A previous fit to pp and p(p)bar elastic scattering data from 13 to 13000 GeV is repeated, with better consideration of the high accuracy 13 TeV data. The conclusion remains that there is no evidence for the existence of an odderon in the small-t data.
