Installation and performance of the 3rd Veto plane at the SND@LHC detector Open
During 2022/2023 the optimal inefficiency of the Veto system of the SND@LHC detector was measured to be (7.8 ± 2.8) × 10 -8 . To reduce this inefficiency, a third Veto plane was installed during the 2023-2024 Year End Technical Stop. In ad…

Observation of Collider Neutrinos without Final State Muons with the SND@LHC Experiment Open
We report the observation of neutrino interactions without final state muons at the LHC, with a significance of 6.4σ. A dataset of proton-proton collisions at s=13.6 TeV collected by SND@LHC in 2022 and 2023 is used, corresponding to an i…

First results from the SND@LHC experiment Open
SND@LHC started taking data at the beginning of Run 3 of the LHC. The experiment is designedto perform measurements with neutrinos produced in proton-proton collisions at the LHC in anenergy range between 100 GeV and 1 TeV. It covers a pre…

Results and Perspectives from the First Two Years of Neutrino Physics at the LHC by the SND@LHC Experiment Open
After rapid approval and installation, the SND@LHC Collaboration was able to gather data successfully in 2022 and 2023. Neutrino interactions from νμs originating at the LHC IP1 were observed. Since muons constitute the major background fo…

SND@LHC: the scattering and neutrino detector at the LHC Open
SND@LHC is a compact and stand-alone experiment designed to perform measurements with neutrinos produced at the LHC in the pseudo-rapidity region of 7.2 < η < 8.4. The experiment is located 480 m downstream of the ATLAS interaction point, …

Observation of Collider Muon Neutrinos with the SND@LHC Experiment Open
We report the direct observation of muon neutrino interactions with the SND@LHC detector at the Large Hadron Collider. A dataset of proton-proton collisions at sqrt[s]=13.6 TeV collected by SND@LHC in 2022 is used, corresponding to an inte…

Sensitivity of the SHiP experiment to dark photons decaying to a pair of charged particles Open
Dark photons are hypothetical massive vector particles that could mix with ordinary photons. The simplest theoretical model is fully characterised by only two parameters: the mass of the dark photon m$_{γ^{\mathrm{D}}}$ and its mixing para…

We propose to build and operate a detector that, for the first time, will measure the process $pp\to\nu X$ at the LHC and search for feebly interacting particles (FIPs) in an unexplored domain. The TI18 tunnel has been identified as a suit…

Measurement of the muon flux for the SHiP experiment Open
The SHiP experiment will search for very weakly interacting particles beyond the Standard Model which are produced in a 400 \GeV/$c$ proton beam dump at the CERN SPS. About $10^{11}$ muons per spill will be produced in the dump. To design …
