چکیده

Studies of photon-photon collisions are reviewed with particular emphasis on new results reported to this conference. These include results on light meson spectroscopy and deep inelastic ey scattering. Considerable work has now been accumulated on resonance production by yy collisions. Preliminary high statistics studies of the photon structure function F$(x,Q2) are given and comments are made on the problems that remain to be solved. 1. General Remarks The advent of high-energy-high-luminosity e+estorage rings has led to productive studies of photon-photon collisions. As shown' by C. F. Weizsacker and E. .I. Will iams, the electromagnetic field produced by a charge moving with relativistic velocity is equivalent to a flux of virtual photons with a characteristic spectrum,

Photon - Photon Collisions at the Next Linear Collider : Theory

The collisions of photons at a high energy electron-positron collider provide a comprehensive laboratory for testing QCD, electroweak interactions, and extensions of the standard model. It is expected that by using back-scattered laser beams, that the effective luminosity and, energy of photon-photon collisions will be comparable to that of the primary c+e-collisions. In this talk, I will focus...

Physics Opportunities in Ultraperipheral Heavy Ion Collisions at Lhc

Due to coherence, there are strong electromagnetic fields of short duration in very peripheral heavy ion collisions. They give rise to photon-photon and photon-nucleus collisions with high flux up to an invariant mass region hitherto unexplored experimentally. Photon-photon and photon-hadron physics at various invariant mass scales are discussed. Due to the very strong electromagnetic fields th...

Hadronic photon-photon interactions at high energies.

Photon-photon collisions are investigated in the framework of the two-component Dual Parton Model. The model contains contributions from direct, resolved soft and resolved hard interactions. All free parameters of the model are determined in fits to hadronhadron and photon-hadron cross section data. The model is shown to agree well to hadron production data from hadron-hadron and photon-hadron ...

High Energy Photon–photon Collisions at a Linear Collider∗

High intensity back-scattered laser beams will allow the efficient conversion of a substantial fraction of the incident lepton energy into high energy photons, thus significantly extending the physics capabilities of an ee linear collider. The annihilation of two photons produces C = + final states in virtually all angular momentum states. An important physics measurement is the measurement of ...
