Further studies on the physics potential of an experiment using LHC neutrinos

Understand

We discuss an experiment to investigate neutrino physics at the LHC in Run 3, with emphasis on tau flavour.

• As described in our previous paper [arXiv:1903.06564v1], the detector can be installed in the decommissioned TI18 tunnel, about 480 m downstream the ATLAS cavern, after the first bending dipoles of the LHC arc.
• In that location, the prolongation of the beam Line-of-Sight from Interaction Point IP1 to TI18 traverses about 100 m of rock.
• The detector intercepts the intense neutrino flux, generated by the LHC beams colliding in IP1, at large pseudorapidity eta, where neutrino energies can exceed a TeV.
