“…There are numerous other potentially interesting topics in the neutrino sector that FASERν could be sensitive to including neutrino tridents [151][152][153][154] which are also a portal to new physics [155,156], neutrino Non-Standard Interactions [157][158][159], neutrino decay [160][161][162] and the weak mixing angle.…”

Neutrinos are copiously produced at particle colliders, but no collider neutrino has ever been detected. Colliders produce both neutrinos and anti-neutrinos of all flavors at very high energies, and they are therefore highly complementary to those from other sources. FASER, the Forward Search Experiment at the LHC, is ideally located to provide the first detection and study of collider neutrinos. We investigate the prospects for neutrino studies with FASERν, a proposed component of FASER, consisting of emulsion films B. Denton and Callum Wilkinson: FASER Associate.

We consider generic neutrino dipole portals between left-handed neutrinos, photons, and righthanded heavy neutral leptons (HNL) with Dirac masses. The dominance of this portal significantly alters the conventional phenomenology of HNLs. We derive a comprehensive set of constraints on the dipole portal to HNLs by utilizing data from LEP, LHC, MiniBooNE, LSND as well as observations of Supernova 1987A and consistency of the standard Big Bang Nucleosynthesis. We calculate projected sensitivities from the proposed high-intensity SHiP beam dump experiment, and the ongoing experiments at the Short-Baseline Neutrino facility at Fermilab. Dipole mediated Primakoff neutrino upscattering and Dalitz-like meson decays are found to be the main production mechanisms in most of the parametric regime under consideration. Proposed explanations of LSND and MiniBooNE anomalies based on HNLs with dipole-induced decays are found to be severely constrained, or to be tested in the future experiments.

“…Other measurements by CCFR [8] and NuTeV [9] at larger energies soon followed. As the measurement of trident events may provide a sensitive test of the weak sector [10] as well as placing constraints on physics beyond the SM [8,[11][12][13][14][15][16] it is relevant to investigate how to probe the other modes. This was recognized by the authors of Ref.…”

Neutrino trident scattering is a rare Standard Model process where a chargedlepton pair is produced in neutrino-nucleus scattering. To date, only the dimuon final-state has been observed, with around 100 total events, while the other channels are as yet unexplored. In this work, we compute the trident production cross section by performing a complete four-body phase space calculation for different hadronic targets. This provides a correct estimate both of the coherent and the diffractive contributions to these cross sections, but also allows us to address certain inconsistencies in the literature related to the use of the Equivalent Photon Approximation in this context. We show that this approximation can give a reasonable estimate only for the production of dimuon final-states in coherent scattering, being inadmissible for all other cases considered. We provide estimates of the number and distribution of trident events at several current and future near detector facilities subjected to intense neutrino beams from accelerators: five liquid-argon detectors (SBND, µBooNE, ICARUS, DUNE and νSTORM), the iron detector of T2K (INGRID) and three detectors made of composite material (MINOS, NOνA and MINERνA). We find that for many experiments, trident measurements are an attainable goal and a valuable addition to their near detector physics programme.
