Description

The electromagnetic production of a dilepton pair in the muon - ion scattering, usually denoted as muon trident process, is investigated considering the feasibility of studying processes induced by muons at LHC using FASER$\nu$ and FASER$\nu$2 detectors. The total and differential cross - sections are estimated taking into account of the Bethe-Heitler and bremsstrahlung channels, and predictions for the event rates expected for muon - tungsten ($\mu W$) collisions at the LHC energies are calculated. Our results indicate that the observation of the muon trident process is feasible at these detectors. In particular, our results indicate that the electromagnetic production of $\tau^+ \tau^-$ pairs in the $\mu W$ scattering can, in principle, be observed for the first time ever at the LHC. In addition, we made predictions for the production of QED bound states.
