| Résumé : | We present an experimental study of the ep→eγ+p and ep→eγ+X processes using data recorded by the H1 detector in 1993 at the electron-proton collider HERA. These processes are employed to measure the luminosity with an accuracy of 4.5 %. A subsample of the ep→eγ+X events in which the hard photon is detected at angles θγ′ ≤ 0.45 mrad with respect to the incident electron direction is used to verify experimentally the size of radiative corrections to the ep→eX inclusive cross section and to investigate the structure of the proton in the Q2 domain down to 2 GeV2, lower than previously attained at HERA. © 1995 Springer-Verlag. |
