The present knowledge of the structure of the photon is presented with emphasis on measurements of the photon structure obtained from deep inelastic electron-photon scattering at e + e − colliders. This review covers the leptonic and hadronic structure of quasi-real and also of highly virtual photons, based on measurements of structure functions and differential cross-sections. Future prospects of the investigation of the photon structure in view of the ongoing LEP2 programme and of a possible linear collider are addressed. The most relevant results in the context of measurements of the photon structure from photon-photon scattering at LEP and from photonproton and electron-proton scattering at HERA are summarised.

The phenomenology of hadronic interactions at high energy, which developed in the 1960s, is briefly explained. Following the introduction of Quantum Chromodynamics (QCD) and its success in elucidating the nature of nucleon structure in the 1970s, experimental results, both new and not so new, are described which, when taken together, provide insight into the structure of hadrons and of the chromodynamic mechanisms responsible for their interactions.

Modern high-energy physics experiments collect data using dedicated complex multi-level trigger systems which perform an online selection of potentially interesting events. In general, this selection suffers from inefficiencies. A further loss of statistics occurs when the rate of accepted events is artificially scaled down in order to meet bandwidth constraints. An offline analysis of the recorded data must correct for the resulting losses in order to determine the original statistics of the analysed data sample. This is particularly challenging when data samples recorded by several triggers are combined. In this paper we present methods for the calculation of the offline corrections and study their statistical performance. Implications on building and operating trigger systems are discussed.
