Status of Layout Studies for Fixed-Target Experiments in Alice Based on Crystal-Assisted Halo Splitting
/ Patecki, Marcin (Warsaw U. of Tech.) ; Fomin, Alex (CERN) ; Kikoła, Daniel (Warsaw U. of Tech.) ; Mirarchi, Daniele (CERN) ; Redaelli, Stefano (CERN)
The Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN) is the world largest and most powerful particle accelerator colliding beams of protons and lead ions at energies up to 7 TeV and 2.76 TeV, respectively. ALICE is one of the detector experiments optimised for heavy-ion collisions. [...]

/ Patecki, Marcin (Warsaw U. of Tech. (main)) ; Fomin, Alex (CERN) ; Hermes, Pascal (CERN) ; Kikoła, Daniel (Warsaw U. of Tech. (main)) ; Mirarchi, Daniele (CERN) ; Redaelli, Stefano (CERN)
The Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN) is the world’s largest and most powerful particle accelerator colliding beams of protons and lead ions at energies up to 7 TeV and 2.76 TeV, respectively. ALICE is one of the detector experiments optimised for heavy-ion collisions. [...]

Heavy-flavour studies with a high-luminosity fixed-target experiment at the LHC
/ Trzeciak, Barbara (Prague, Tech. U.) ; Brodsky, S.J. (SLAC) ; Cavoto, G. (INFN, Rome ; Rome U.) ; Da Silva, C. (Los Alamos) ; Echevarria, M.G. (UCM, Madrid, Dept. Phys.) ; Ferreiro, E.G.

(Warsaw U. of Tech.) et al.
Extraction of the multi-TeV proton and lead LHC beams with a bent crystal or by using an internal gas target allows one to perform the most energetic fixed-target experiment ever. $pp$, pd and $p$A collisions at $\sqrt{s_{\rm{NN}}}$ = 115 GeV and Pb$p$ and PbA collisions at $\sqrt{s_{\rm{NN}}}$ = 72 GeV can be studied with high precision and modern detection techniques over a broad rapidity range.

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.

Ultra-peripheral-collision studies in the fixed-target mode with the proton and lead LHC beams
/ Yamanaka, Nodoka (Orsay, IPN) ; Hadjidakis, C. (Orsay, IPN) ; Kikoła, D. (Warsaw U. of Tech.) ; Lansberg, J.P. (Orsay, IPN) ; Massacrier, L. (Orsay, IPN) ; Echevarria, M.G.

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..

A Fixed-Target Programme at the LHC: Physics Case and Projected Performances for Heavy-Ion, Hadron, Spin and Astroparticle Studies

(Jefferson Lab ; Pavia U. ; INFN, Pavia) et al.
We review the context, the motivations and the expected performances of a comprehensive and ambitious fixed-target program using the multi-TeV proton and ion LHC beams. We also provide a detailed account of the different possible technical implementations ranging from an internal wire target to a full dedicated beam line extracted with a bent crystal. [...]
