Description
SND@LHC is a compact experiment which is performing measurements with neutrinos produced at the LHC in a hitherto unexplored pseudo-rapidity region of 7.2 < 𝜂 < 8.4, complementary to all the other experiments at the LHC. The experiment is located 480 m downstream of IP1 and the detector is composed of a hybrid system based on an 800 kg target mass of tungsten plates, interleaved with emulsion and electronic trackers, followed downstream by a calorimeter and a muon system. The configuration allows efficiently distinguishing between all three neutrino flavours, opening a unique opportunity to probe physics of heavy flavour production at the LHC in the region that is not accessible to ATLAS, CMS and LHCb. This region is of particular interest for future circular colliders and for predictions of very high-energy atmospheric neutrinos. The detector has been taking data during the LHC Run 3. The recently approved upgrade of the detector consists of two major novelties: the addition of a magnet for the separation between neutrinos and anti-neutrinos and the use of silicon technology to cope with the high instantaneous luminosity. We shall review the first experimental results and the plans for the upgrade to operate at the high-luminosity LHC. A new era of collider neutrino physics just started.
