Search for Odderon induced contributions to exclusive Meson Photoproduction at HERA
J. Olsson (for the H1 collaboration)

TL;DR
This study searched for Odderon contributions in exclusive meson photoproduction at HERA but found no evidence, setting upper limits below theoretical predictions, while confirming expected cross sections for other processes.
Contribution
First experimental search for Odderon effects in exclusive meson photoproduction at HERA, establishing upper limits below theoretical expectations.
Findings
No Odderon signals observed within the studied kinematic region.
Upper limits on cross sections are below theoretical model predictions.
Confirmed expected cross sections for $ ext{ω}$ and $ ext{ωπ}^0$ photoproduction.
Abstract
Odderon induced contributions to exclusive photoproduction of , and have been searched for at HERA, using the multiphoton decays of these mesons. No indication for such contributions was found, in a kinematic region defined by the average photon-proton centre-of-mass energy GeV, photon virtualities GeV and GeVGeV, where t is the squared momentum transfer at the proton vertex. The measured upper limits for the cross sections, nb, nb and nb, all at 95% CL, are lower than the predictions by a theoretical model. Exclusive photoproduction of and , in the…
