In this seminar, I will review a number of recent ideas* put forward in favour of a fixed-target programme at the LHC – AFTER@LHC- dedicated to heavy-ion, hadron, spin and astroparticle physics. By using an internal (polarised) gas target or by extracting the beam with a bent crystal, the multi-TeV LHC beams allow one to perform the most energetic fixed-target experiments ever with which one can access the essentially uncharted backward kinematics with detectors similar to LHCb or ALICE.<\/p>

In particular we argue that this allows one to study \/pp\/, \/pd\/ and \/pA\/ collisions at sqrt(s_NN) \u2243 115 GeV and Pb\/p\/ and Pb\/A\/ collisions at sqrt(s_NN) \u224372 GeV with extremely high precision with modern detection techniques. Such studies, including<\/span><\/p>

\u00a0– single transverse-spin asymmetries for hard and rare processes,<\/span><\/p>

\u00a0– suppression of heavy-flavours and quarkonia as well as azimuthal<\/p>

\u00a0 \u00a0asymmetries down to the target rapidity in heavy-ion collisions,<\/p>

\u00a0– cold-nuclear matter effects,<\/p>

\u00a0– the physics involved in ultra-peripheral hadron and ion collisions,<\/p>

\u00a0– far backward gluon and heavy-quark sensitive processes,<\/p>

\u00a0– vector-boson production near threshold …,<\/p>

would greatly complement collider experiments, in particular those of the Electron-Ion Collider project or RHIC (with luminosities larger by 1 to 3 orders of magnitude).<\/span><\/p>

Such a mode indeed allows for a broad physics programme, covering the large-\/x\/ QCD frontier for particle and astroparticle physics, as well as spin and heavy-ion physics with respectively a polarised target and the LHC lead beam.<\/p>

\u00a0<\/p>
