The detection of collider neutrinos will provide new insights about neutrino production,
propagation, and interactions at TeV energies, the highest human-made energies ever
observed. During run 3 of the LHC, the FASER experiment is expected to detect roughly 10

show that, even without processing the emulsion data, low-level input provided by the

The detection of collider neutrinos will provide new insights about neutrino production, propagation, and interactions at TeV energies, the highest human-made energies ever observed. During run 3 of the LHC, the FASER experiment is expected to detect roughly collider neutrinos using its emulsion-based neutrino detector . In this study, we show that, even without processing the emulsion data, low-level input provided by the electronic detector components of FASER and will be able to establish a discovery of collider neutrinos with as little as of integrated luminosity. These results foreshadow the possible early discovery of collider neutrinos in LHC run 3.
