  SND@LHC is a compact experiment to perform measurements with neutrinos produced at the LHC. The LHC provides high energy neutrinos above the energies of previously detected man-made neutrinos. The SND@LHC detector is located 480 m downstream of the ATLAS interaction point along the beam collision axis. It covers the unexplored pseudo-rapidity range of  7.2  <  η <  8.4. The detector is able to distinguish interactions among all three neutrino flavors.

In the high pseudo-rapidity range, electron neutrinos and anti-neutrinos mostly come from charmed-hadron decays. The measurement of charmed-hadron production in the SND@LHC pseudo-rapidity range can be used to constrain the gluon parton density function in an unexplored region of very-small x.

The SND@LHC experiment is also sensitive to Feebly Interacting Particles (FIPs), such as dark photons, through scattering off atoms in the detector target. Thus, it could open a new window on new physics beyond the standard model.
