Description
The workshop aims at discussing the physics, experimental results, and perspectives on photon-induced processes at HERA (ep), RHIC (electromagnetic aka. "ultraperipheral" AA), Tevatron (gamma-p,pbar, gamma-gamma), and LHC (ultraperipheral AA, photon-photon collisions in pp, ...) Organization: Talks and discussions will be organized around the following main topics: - Overview theoretical and experimental talks on photoproduction at RHIC, HERA, Tevatron, and prospects for LHC. - Inclusive and exclusive photoproduction at HERA (dijets, heavy-quarks, vector mesons, ...). - Vector-meson and hard- photoproduction in ultraperipheral (UPC) ion-ion at RHIC and LHC, with emphasis on the high gluon density regime at small-x in the nucleus. - Photoproduction in ppbar,pp collisions at Tevatron and LHC. - Two-photon processes (tests of QED in strong field regime in UPC, pp luminosity tool at LHC, triple and quartic gauge coupling gamma-gamma studies ...).

      NA60 experimental capabilities for ultraperipheral collisions 25m
      Speaker: Carlos Lourenco
      \documentclass[12pt]{article} \begin{document} \begin{center} \vskip 0.5cm {\bf {\Large NA60 experimental capabilities\\ for ultra-peripheral collisions}}\\ {\bf \large Carlos Louren\c{c}o\\ CERN-PH, Geneva, Switzerland} \end{center} In this presentation we introduce the NA60 experiment, in terms of concept, detectors and performance, placing emphasis on issues of relevance for the tagging of Ultra-Peripheral Collisions, which is necessarily done in rather different ways in a fixed-target collision geometry with respect to the presently more common collider experiments. We also mention some specific features affecting the NA60 case, such as beam and interaction pile-up, detector resolutions, etc. In summary, it seems likely that the available NA60 In-In data can provide useful information on dimuon production in Ultra-Peripheral Collisions. \end{document}
