An integrated flux-symmetric spectrometer-magnet system for the SND@LHC experiment upgrade / SND@LHC Collaboration
The proposed upgrade of the SND@LHC experiment for the High Luminosity phase of the LHC (HL-LHC) will strongly benefit from the presence of a magnetized region, allowing for muon momentum and chargemeasurement. In this paper we describe an iron core magnet system that is partly integrated with the calorimeter and that is designed to respect the strict constraints from the available space in the experimental cavern, power consumption, and field requirements.Semi-analytical tools are introduced to explore the parameter space, in order to define the primary design options.

We report the observation of neutrino interactions without final state muons at the LHC, with a significance of 6.4\,$\sigma$. A data set of proton-proton collisions at $\sqrt{s}= 13.6$\,TeV collected by \SND in 2022 and 2023 is used, corresponding to an integrated luminosity of 68.6\,fb$^{-1}$. [...]

Over the six months since the submission of the AdvSND LoI \cite{ADVSND_LOI}, the Collaboration has been intensively discussing with the CERN civil engineering team and the High Luminosity LHC (HL LHC) planning officers to fully understand the constraints related to the civil engineering modifications required for TI18 [...]

Results and perspectives from the first two years of neutrino physics at the LHC by the SND@LHC experiment / SND@LHC Collaboration
After a rapid approval and installation, the SND@LHC Collaboration was able to take data successfully in 2022 and 2023. Neutrino interactions from $\nu_{\mu}$s originating at the LHC IP1 were observed. [...]

BDF/SHiP at the ECN3 high-intensity beam facility / SHiP Collaboration
The BDF/SHiP collaboration has proposed a general-purpose intensity-frontier experimental facility operating in beam-dump mode at the CERN SPS accelerator to search for feebly interacting GeV-scale particles and to perform measurements in neutrino physics. [...]

Measurement of the muon flux at the SND@LHC experiment / SND@LHC Collaboration
The Scattering and Neutrino Detector at the LHC (\SND) is a compact standalone experiment, which started taking data at the beginning of Run 3 of the LHC. The experiment is designed to perform measurements with neutrinos produced in proton-proton collisions at the LHC in an energy range between~100~GeV and~1~TeV, and a previously unexplored pseudo-rapidity range of \mbox{$7.2<\eta<8.4$} [...]

Observation of collider muon neutrinos with the SND@LHC experiment / SND@LHC Collaboration
We report the direct observation of muon neutrino interactions with the \SND detector at the Large Hadron Collider. A data set of proton-proton collisions at $\sqrt{s} = 13.6\,$TeV collected by \SND in 2022 is used, corresponding to an integrated luminosity of 36.8$\,\rm{fb}^{-1}$. [...]

RPC-based Muon Identification System for the neutrino detector of the SHiP experiment / Albanese, R (INFN, Naples ; Naples U.) ; Alexandrov, A (INFN, Naples) ; Buontempo, S (INFN, Naples) ; Choi, K Y (Sungkyunkwan U.) ; Congedo, L (INFN, Bari ; Bari U.) ; de Asmundis, R (INFN, Naples) ; De Lellis, G (INFN, Naples ; Naples U.) ; de Magistris, M (INFN, Naples ; Naples U.) ; De Robertis, G (INFN, Bari) ; De Serio, M (INFN, Bari ; Bari U.) et al.
The SHiP experiment has been proposed at CERN to shed light on phenomena still unexplained in the framework of the Standard Model, such as the nature of dark matter, the baryonic asymmetry of the Universe and the neutrino oscillations, searching for hints of New Physics. A section of the detector will be dedicated to the study of neutrino physics with special emphasis on tau neutrino properties, still very poorly measured. [...]

Updated constraints on sterile neutrino mixing in the OPERA experiment using a new $\nu_e$ identification method / OPERA Collaboration
This paper describes a new $\nu_e$ identification method specifically designed to improve the low-energy ($< 30\,\mathrm{GeV}$) $\nu_e$ identification efficiency attained by enlarging the emulsion film scanning volume with the next generation emulsion readout system. A relative increase of 25-70% in the $\nu_e$ low-energy region is expected, leading to improvements in the OPERA sensitivity to neutrino oscillations in the framework of the 3 + 1 model. [...]
