Abstract The Scattering and Neutrino Detector at the LHC (SND@LHC) is a compact and standalone experiment, which started taking data in the beginning of Run 3 of the LHC. The experiment is designed to perform measurements with neutrinos produced in proton-proton collisions at the LHC in an energy range between 100 GeV–1 TeV and hitherto unexplored pseudo-rapidity region of 7.2 < 𝜂 < 8.4, complementary to all the other experiments at the LHC. The detector, located 480 m downstream of the ATLAS interaction point in the TI18 tunnel, comprises a veto system followed by an 830 kg target mass of tungsten plates, interleaved with emulsion and Scintillating Fiber (SciFi) electronic trackers, and then a calorimeter and a downstream muon system (DS).Using a data set collected by the SND@LHC electronic detectors in the first year of detector operation in 2022, eight muon neutrino candidates have been identified through their charged- current interactions in the detector with an estimated background of 0.086 events, yielding a significance of 6.8 standard deviations for the observed 𝜈 𝜇 signal. To facilitate the background assessment, the muon flux in the TI18 tunnel has been determined. These proceedings describe the first SND@LHC neutrino analysis and background estimation.
