Workshop on "Photoproduction at collider energies: from RHIC and HERA to LHC"

15 Jan 2007, 09:00 → 19 Jan 2007, 18:00 Europe/Zurich

ECT* Trento

Baur Gerhard (Juelich), David d'Enterria (CERN), Joakim Nystrand (Univ. Bergen), Mark Strikman (Penn. State Univ.), Spencer Klein (LBNL)

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 ...).

15:10 → 15:35 NA60 experimental capabilities for ultraperipheral collisions

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}
