Description
SND@LHC is a compact and stand-alone experiment to perform measurements with neutrinos produced at the LHC in a hitherto unexplored pseudo-rapidity region of 7.2 < 𝜂 < 8.6,
complementary to all the other experiments at the LHC. The experiment is located 480 m downstream of IP1 in the unused TI18 tunnel.
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 also for future circular colliders and for predictions of very high-energy atmospheric neutrinos.
The detector concept is also well suited to searching for Feebly Interacting Particles via signatures of scattering in the detector target.
Since 2022 the experiment has collected 309 fb-1 of data at 97% efficiency. Using data from the electronic detectors,
muon neutrino interactions were found as well as solid evidence for electron neutrino interactions.
In this talk we shall present results from 2025 data, including an analysis of the muon flux which has significantly increased our understanding of the behaviour of the LHC beams.
The reconstruction of the emulsion data has now achieved a sub micrometer resolution and significant progress was made with vertex finding and electronic shower recognition
