Studying neutrino properties is one of the hottest points in modern particle physics. A few years ago, CERN decided to concentrate on the LHC and to stop the accelerator neutrino programme. However, some new experiments were proposed recently at CERN aimed to study neutrinos in the regions where their properties are poorly known or unexplored.

At the seminar, a brief overview will be given of several CERN experiments (FASER, SND@LHC, XSEN, DsTau/NA65, SHiP) aimed to register ultra-high-energy neutrinos from the LHC, to measure the cross section of the ν_τ scattering off a nucleon, to search for intrinsic charm in a nucleon, etc. The experimental method is based on high-resolution (~\(1\mu m\) and better) nuclear emulsion detectors for effective registration of short-lived particles. The use of nuclear emulsion in modern experiments became popular again due to intensive progress in the high-speed (~0.5 m²/hour and faster) emulsion readout technique based on powerful automatic scanning stations.

The DsTau (NA65) experiment aimed to study tau-neutrino production in proton-nucleus interactions at the CERN SPS will be described in more detail. The main data sample will be collected in 2021-2022. The data analysis will be a challenge considering high track density (~10⁵-10⁶/cm²) and the amount of data to be processed. The status of the pilot run data analysis and prospects of mass data processing, which requires resources of big data storage and distributed parallelization of computationally intensive tasks, will be presented as well.
