Observation of collider muon neutrinos with the SND@LHC experiment
We report the direct observation of muon neutrino interactions with the
SND@LHC detector at the Large Hadron Collider. A data set of proton-proton
collisions at TeV collected by SND@LHC in 2022 is used,

is based on information from the active electronic components of the SND@LHC
detector, which covers the pseudo-rapidity region of ,
inaccessible to the other experiments at the collider. Muon neutrino candidates
are identified through their charged-current interaction topology, with a track
propagating through the entire length of the muon detector. After selection
cuts, 8 interaction candidate events remain with an estimated
background of 0.076 events, yielding a significance of seven standard
deviations for the observed signal.Comment: Submitted to Phys. Rev. Let
