SND@LHC (Scattering and Neutrino Detector at the LHC) is a compact experiment installed in the far-forward region of interaction point 1 of the LHC, covering the pseudorapidity range 7.2 < η < 8.4. The experiment has operated since the start of Run 3 with a hybrid design combining an emulsion-tungsten target with scintillating-fibre tracking, a hadronic calorimeter, and a muon system, allowing for the identification of the three neutrino flavours via deep inelastic scattering in the target.

 

In this seminar, the collaboration's physics results from Run 3 will be presented, including the first observation of neutrinos produced at a collider, obtained concurrently with the FASER experiment, and subsequent measurements of neutrino interactions. The connection of these measurements to forward heavy-flavour production will be discussed as well as the prospects for probing physics beyond the Standard Model in this unique phase space. The ongoing upgrade for Run 4 will also be discussed, in which the detector instrumentation will be replaced by high-granularity silicon sensors, the muon system will be magnetised, and plastic scintillator timing layers will be added.

 

Refreshments will be served at 10:30
