(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.

Using multiple engines in the Virtual Monte Carlo package
/ Volkel, Benedikt (U. Heidelberg (main) ; CERN) ; Morsch, Andreas (CERN) ; Hřivnáčová, Ivana (IJCLab, Orsay) ; Grosse-Oetringhaus, Jan Fiete (CERN) ; Wenzel, Sandro (CERN)
The Virtual Monte Carlo (VMC) package provides a unified interface to different detector simulation transport engines such as GEANT3 and GEANT4. It has been in production use in various experiments but so far the simulation of one event was restricted to the usage of a single chosen engine. [...]

Pittsburgh (main)) ; Bernard, Denis (Ecole Polytechnique) ; Bordage, Marie-Claude (CRCT, Toulouse) ; Burkhardt, Helmut (CERN) ; Dondero, Paolo (Columbus Supercond., Genova) ; Grichine, Vladimir (Lebedev Inst.) ; Guatelli, Susanna (Wollongong U.) et al.
The Geant4 electromagnetic (EM) physics sub-packages are a component of LHC experiment simulations. During long shutdown 2 for LHC, these packages are under intensive development and we report progress of EM physics in Geant4 versions 10.5 and 10.6, which includes faster computation, more accurate EM models, and extensions to the validation suite.

Physics perspectives with AFTER@LHC (A Fixed Target ExpeRiment at LHC)
/ Massacrier, L. (Orsay, IPN) ; Anselmino, M. (INFN, Turin ; Turin U.) ; Arnaldi, R. (INFN, Turin ; Turin U.) ; Brodsky, S.J. (SLAC) ; Chambert, V. (Orsay, IPN) ; Da Silva, C. (Los Alamos) ; Didelez, J.P. (Orsay, IPN) ; Echevarria, M.G. (INFN, Pavia) ; Ferreiro, E.G. (Santiago de Compostela U.) ; Fleuret, F. (Ecole Polytechnique) et al.
AFTER@LHC is an ambitious fixed-target project in order to address open questions in the domain of proton and neutron spins, Quark Gluon Plasma and high-$x$ physics, at the highest energy ever reached in the fixed-target mode. Indeed, thanks to the highly energetic 7 TeV proton and 2.76 A.TeV lead LHC beams, center-of-mass energies as large as $\sqrt{s_{NN}}$ = 115 GeV in pp/pA and $\sqrt{s_{NN}}$ = 72 GeV in AA can be reached, corresponding to an uncharted energy domain between SPS and RHIC.

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
/ Hadjidakis, Cynthia (Orsay, IPN) ; Brodsky, S.J. (SLAC) ; Cavoto, G. (INFN, Rome ; Rome U.) ; Da Silva, C. (Los Alamos) ; Donato, F. (Turin U. ; INFN, Turin) ; Echevarria, M.G. (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.

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

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. [...]
