Measurements of diffractive processes at HERA
Aharon Levy
In this talk, the recent data on diffractive electron-proton interactions at HERA are reviewed. The question of diffraction as a soft or hard process is addressed and discussed in…
The legacy of HERA - the first decade
Aharon Levy
The ep HERA collider started operation in summer of 1992. This talk summarizes some of the highlights of physics results obtained since then and discusses their impact on our under…
The proton and the photon, who is probing whom in electroproduction?
Aharon Levy
The latest results on the structure of the proton and the photon as seen at HERA are reviewed while discussing the question posed in the title of the talk.
The structure of the Troika: Proton, Photon and Pomeron, as seen at HERA
Aharon Levy
HERA, the electron-proton collider, enables to probe the proton with a high resolving power due to the deep inelastic scattering reactions at high values. In the low re…
The ALLM parameterization of sigma_{tot}(gamma* p) - an update
Halina Abramowicz, Aharon Levy
The ALLM parameterization of sigma_{tot}(gamma* p) has been updated by using all published F_2 data to determine its parameters. The fit yields a chi^2/ndf of 0.97 for the 1356 dat…
The transition from the photoproduction to the DIS region
Aharon Levy
This is a review of the existing ideas in modelling the transition from the photoproduction () to the deep inelastic scattering region. The available data of the proton st…
