| Abstract |
This paper reports on cross section measurements made at HERA for the reactions gamma p -> omega p and gamma p-> omega pi^0 X, and on searches for the reactions gamma p -> pi^0 N^*, gamma p -> f_2(1270) X, and gamma p -> a_2^0(1320) X, where N^* denotes an excited nucleon state. The average photon - proton centre-of-mass energy at HERA were = 200 GeV and 210 GeV. Cross sections for the Pomeron - mediated reactions were determined in agreement with previous measurements and theoretical expectations. Processes mediated by Odderon - photon fusion could not be observed; upper limits on cross sections are below predictions from non-perturbative QCD models. |
