It provides the first detailed estimates of neutrino trident cross-sections and event rates at the LHC, considering different flux models and interaction types.

Findings

Neutrino trident process is potentially observable at the FASERν2 detector.

Cross-sections for various leptonic final states are estimated.

Event rate predictions depend on hadronic models for particle production.

Abstract

The neutrino trident scattering process in neutrino - tungsten interactions at the LHC energy regime is investigated, and the cross-sections for different leptonic final states in coherent and incoherent interactions are estimated. Furthermore, the associated number of eventsat FASER$\nu$2 detector is estimated considering different predictions for the flux of incident neutrinos on the detector, based on distinct hadronic models for the particle production in $pp$ collisions at ultra-forward rapidities. Our results indicate that the observation of the neutrino trident process is, in principle, feasible at the Forward Physics Facility.
