We plan to discuss the question of the physics impact and feasibility of a fixed target experiment on the LHC beam, where a small fraction of the beam (of the order of a few per cent) would be extracted. With a 7(2.75) TeV proton (Pb) beam, the center-of-mass energy would reach 115(72) GeV. Such a setup would give access to the very high (small) xB region in the target (projectile). It would give the possibility to study rare processes, novel spin-correlations, high-xF dynamics, diffractive physics, nPDFs and nuclear phenomena such as shadowing and absorption, as well as novel spectroscopy of hadrons carrying multiple heavy quarks with high precision. In addition, Pb+Pb runs at sqrt(s)~72 GeV would give access to the QGP physics at an intermediate energy between SPS and RHIC energies.
Theory inputs will be most welcome for this meeting.
