/ Galluccio, Francesca (Universita e sezione INFN di Napoli (IT)) ; Hadjidakis, Cynthia (Centre National de la Recherche Scientifique (FR)) ; Kurepin, Alexander (Institute for Nuclear Research, Moscow) ; Massacrier, Laure (Centre National de la Recherche Scientifique (FR)) ; Porteboeuf, S (Centre national de la recherche scientifique (FR)) ; Pressard, Kevin (Centre national de la recherche scientifique (FR)) ; Scandale, Walter (CERN) ; Topilskaya, Natalia (Institute for Nuclear Research, Moscow) ; Trzeciak, Barbara (Utrecht University) ; Uras, Antonio (Centre national de la recherche scientifique (FR)) et al.
A fixed-target programme in the ALICE experiment using the LHC proton and lead beams offers many physics opportunities related to the parton content of the nucleon and nucleus at high-$x$, the nucleon spin and the Quark-Gluon Plasma. We investigate two solutions that would allow ALICE to run in a fixed-target mode: the internal solid target coupled to a bent crystal and the internal gas target. [...]

Slow extraction using the third-integer resonance and thin electrostatic septa as used in the SPS to serve the North Area is a process with inherent beam loss. [...]

Spin Physics with a fixed-target experiment at the LHC
/ Echevarria, M.G. (INFN, Pavia) ; Brodsky, S.J. (SLAC) ; Cavoto, G. (INFN, Rome ; Rome U.) ; Da Silva, C. (Los Alamos) ; Donato, F. (INFN, Turin ; Turin U.) ; Ferreiro, E.G. (Santiago de Compostela U.) ; Hadjidakis, C. (Orsay, IPN) ; Hřivnácová, I. (Orsay, IPN) ; Kikoła, D. (Warsaw U. of Tech.) ; Klein, A. (Los Alamos) et al.
The multi-TeV proton and ion beams of the LHC would allow for the most energetic fixed-target experiment ever. In particular, $pp$, $p$d and $p$A collisions could be performed at $\sqrt{s_{NN}}$ = 115~GeV, as well as Pb$p$ and PbA collisions at $\sqrt{s_{NN}}$ = 72~GeV, in a parasitic way by making use of the already existing LHCb and ALICE detectors in fixed-target mode.

High luminosity fixed-target experiment at the LHC

(INFN, Pavia) ; Ferreiro, E.G. (Santiago de Compostela U.) ; Hřivnáčová, I. (Orsay, IPN) ; Kikola, D. (Warsaw U. of Tech.) ; Klein, A. (Los Alamos) et al.
By extracting the beam with a bent crystal or by using an internal gas target, the multi-TeV proton and lead LHC beams allow one to perform the most energetic fixed-target experiments ever and to study $pp$, $p$d and $p$A collisions at $\sqrt{s_{NN}}=115$ GeV and Pb$p$ and PbA collisions at $\sqrt{s_{NN}}=72$ GeV with high precision and modern detection techniques. Such studies would address open questions in the domain of the nucleon and nucleus partonic structure at high-$x$, quark-gluon plasma and, by using longitudinally or transversally polarised targets, spin physics.

The UA9 experiment at CERN-SPS investigates the manipulation of high energy hadron beams using bent silicon crystals since 2009. Monitoring and characterization of channeled beams in the high energy accelerators environment ideally requires in-vacuum and radiation hard detectors. [...]

Ultra-peripheral-collision studies in the fixed-target mode with the proton and lead LHC beams

We address the physics case related to the studies of ultra-peripheral pH, pPb, PbH, and PbPb collisions in the fixed-target mode at the LHC. In particular, we discuss how one can measure the gluon generalized parton distribution $E_g(x,\xi,t)$ in exclusive $J/psi$ photoproduction with a transversely polarized hydrogen target..

Probing the high-x content of the nuclei in the fixed-target mode at the LHC
/ Kusina, Aleksander (Cracow, INP) ; Hadjidakis, C. (Orsay, IPN) ; Kikola, D. (Warsaw U. of Tech.) ; Lansberg, J.P. (Orsay, IPN) ; Massacrier, L. (Orsay, IPN) ; Echevarria, M.G.

Using the LHCb and ALICE detectors in the fixed-target mode at the LHC offers unprecedented possibilities to study the quark, gluon and heavy-quark content of the proton and nuclei in the poorly known region of the high-momentum fractions. We review our projections for studies of Drell-Yan, charm, beauty and quarkonium production with both detector set-ups used with various nuclear targets and the LHC proton beams. [...]
