Physics at A Fixed Target ExpeRiment (AFTER) using the LHC beams

3 févr. 2013, 18:00 → 13 févr. 2013, 18:55 Europe/Rome

ECT* Trento

Andry Rakotozafindrabe (CEA Saclay, SPhN), Elena Ferreiro (Department of Particle Physics, University of Santiago de Compostela, Spain), Frédéric Fleuret (LLR-Ecole polytechnique, CNRS/IN2P3), Ingo Schienbein (LPSC), Jean-Philippe Lansberg (IPNO - Paris Sud 11), Stanley J. Brodsky (SLAC National Accelerator Laboratory -- Stanford University), Ulrik Uggerhoej (Aarhus U.)

This is an exploratory workshop which aims at studying in detail the opportunity and feasibility of a fixed-target experiment using the LHC beams extracted by a bent crystal.
Complementarity with existing experiments at the LHC, at SPS, at CEBAF, at Fermilab and RHIC will also be the cornerstone of the discussions. The contribution of everyone is therefore welcome.

The workshop will consist of morning sessions with invited speakers and afternoon sessions devoted to work in groups on the following themes:

• nucleon and nucleus pdf extraction in hadronic processes
• spin physics
• QGP physics
• nuclear matter studies in pA
• diffractive physics and ultra-peripheral collisions
• heavy-quark dynamics and spectroscopy at high |xF|
• beam extraction and secondary beams
• studies of the crystal-extraction influence on the machine and detector performance
• target polarization
• modern detector technologies
• event generator and detector simulation
• etc...
