Lack of evidence for an odderon at small t
A Donnachie, P V Landshoff
TL;DR
This study reanalyzes high-energy proton scattering data to investigate the odderon, concluding that current small-t data do not support its existence, despite improved data accuracy.
Contribution
The paper provides a refined analysis of elastic scattering data, strengthening the evidence against the odderon's presence at small momentum transfer.
Findings
No evidence for odderon at small t
High-precision 13 TeV data do not support odderon existence
Reaffirmation of previous conclusions with improved data handling
Abstract
It is fundamental that the phase of an elastic scattering amplitude is related to its energy variation. We repeat a previous fit to proton-proton and proton-antiproton 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
