International Conference on the Structure and the Interactions of the Photon including the 18th International Workshop on Photon-Photon Collisions and the International Workshop on High Energy Photon Linear Colliders

This conference is a part of the series initiated in 1973 in Paris, as an International Colloquium on
Photon-Photon Collisions at Electron-Positron Storage Rings, devoted to the hadronic interaction of photons. The latest Photon conferences took place in Paris (2007), in Warsaw (2005), and in Frascati (2003).
At the conference, recent progress in understanding photon-photon and photon-proton processes will be presented. In addition, recent results on astrophysics and other related topics will be discussed.
This year's conference will have the following sessions:↵

  • Electroweak and new physics
  • Jets and heavy flavours
  • Photon structure
  • Prompt photons
  • Small x, diffraction, and total cross sections
  • Exclusive channels and resonances
  • Vacuum polarisation and light-by-light scattering
  • Low-energy photon experiments
  • Photons in astroparticle physics
  • Photon collider prospects
  • Invited review talks on photon detectors and on research with synchrotron radiation

Prospects of studying photon collisions at the LHC and the physics potential of a future photon linear collider will play an important role in the topical sessions.

The conference takes place from May 11-15, 2009, at DESY (Hamburg site). The beginning is on Monday, May 11, at 9:15 a.m. The conference ends on Friday, May 15, around 13:00.

The conference was sponsored by the German Science Foundation (DFG), DESY and Hamburg University.
