Description
Most existing and proposed high energy neutrino experiments have excellent muon charge identification capabilities, enabling the distinction of $\nu_\mu$ and $\bar \nu_\mu$ charged current interactions. However, distinguishing electrons and positrons from $\nu_e$ and $\bar \nu_e$ interactions is typically impossible, as they interact quickly within the characteristically dense detector material and fail to reach the spectrometer. Nonetheless, installing a compact and cost-effective plastic target right before the spectrometer would enable the first separate measurement of $\nu_e$ and $\bar\nu_e$ cross sections at high energy. When installed at collider neutrino experiments such as FASER, the Forward Physics Facility, or SHiP, the proposed setup would open new opportunities for studying forward particle production at collider neutrino experiments. In particular, it allows constraining forward $\Lambda$ hyperon production at the LHC, thus helping to reduce flux uncertainties.
