Le résumé fourni par la source
We report a measurement of the muon neutrino charged-current (CC) interaction cross section on tungsten using the electronic detectors of the SND@LHC experiment at the CERN Large Hadron Collider. The analysis uses proton–proton collision data at a centre-of-mass energy of √s = 13.6 TeV, corresponding to an integrated luminosity of 68.6 fb^−1 collected during LHC Run 3 in 2022 and 2023. A total of 31 ν_μ CC candidates are selected against an expected background of 5.0 ± 1.1 events, consistent with a signal expectation of 24+10−9 events. The signal strength is measured to be ˆμ = 1.09+0.72−0.37, and the combined muon neutrino and anti-neutrino CC cross section on tungsten is determined to be σ(ν_μ + ¯ν_μ) = (37+24−12) × 10^−35 cm^2 at a median energy of 228 GeV. In addition, a calorimetric measurement of the hadronic energies of the neutrino candidate event s is performed, making use of calibration data from dedicated test-beam campaigns.
