Physics at a Fixed-Target Experiment Using the LHC Beams

Description

Fixed-target experiments (FTE) have brought essential contributions to particle and nuclear physics. They have led to particle discoveries (Ω, J/ψ, ϒ,...) and evidence for the novel dynamics of quarks and gluons in heavy-ion collisions. In accessing high xF and in offering options for (un-) polarised proton and nuclear targets, they have also led to the observation of surprising QCD phenomena. They offer specific advantages compared to collider experiments: access to high xF, high luminosities, target versatility, and polarisation.

The LHC 7 TeV protons on targets release a c.m.s. energy close to 115 GeV (72 GeV with Pb), in a range never explored so far, significantly higher than that at SPS and not far from RHIC. The production of quarkonia, DY, heavy flavours, jets, and γ in pA collisions can be studied with statistics previously unheard of and in the backward region, xF < 0, which is uncharted. High precision QCD measurements can also obviously be carried out in pp and pd collisions with H 2 and D 2 targets. With the 50 TeV protons of the future circular collider (FCC), the c.m.s. energy could reach 300 GeV for original studies of W and Z boson, and perhaps H 0, production in pp and pA collisions.

With the LHC Pb beam, one can study the quark-gluon plasma (QGP) from the viewpoint of the nucleus rest frame after its formation. Thanks to modern technologies, studies of, for instance, direct γ and quarkonium P-waves production in heavy-ion collisions can be envisioned.

Polarising the target allows one to study single-spin correlations including the Sivers effect, hence, the correlation between the parton k T and the nucleon spin.

We intend to publish a special issue on the physics at such a FTE using the LHC or FCC beams. The editors welcome original research articles and review articles from both theorists and experimentalists.

Potential topics include, but are not limited to:

  • Heavy-quark and gluon content at large x
  • TMDs and single-spin asymmetries
  • Heavy-flavour studies in pA and AA collisions at FTEs
  • W, Z, and H 0 production near threshold
  • Target polarisation
  • Secondary beams
  • Simulation tools for high-energy physics
  • Beam collimation and extraction with bent crystals
  • Machine feasibility and radiological aspects
  • Connection between UHECR studies and FTEs
