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…

Computing and machine learning for the SHiP experiment Open
The recently approved SHiP experiment aims to search for new physics at the intensity frontier, including feebly interacting particles and light dark matter, and perform precision measurements of tau neutrinos. To fulfil its full discovery…

Nucleon charges and $σ$-terms in lattice QCD Open
We determine the nucleon axial, scalar and tensor charges and the nucleon $σ$-terms using twisted mass fermions. We employ three ensembles with approximately equal physical volume of about 5.5~fm, three values of the lattice spacing, appro…

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…

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…

Feebly-Interacting Particles: FIPs 2022 Workshop Report Open
Particle physics today faces the challenge of explaining the mystery of dark matter, the origin of matter over anti-matter in the Universe, the origin of the neutrino masses, the apparent fine-tuning of the electro-weak scale, and many oth…

Optimising the Active Muon Shield for the SHiP Experiment at CERN Open
The SHiP experiment is designed to 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. The critical challenge for this experiment is to keep the Standar…
