Studying neutrino properties in accelerator experiments NOvA, T2K, DsTau, FASER
Measurement of the neutrino mass hierarchy, CP violation and other parameters of neutrino oscillations in the NOvA and T2Klong-baseline accelerator experiments. Study of tau leptons production via $D_{s}$ meson production and decay in proton-nucleus collisions at 400 GeV/c (the DsTau experiment). Study of high-energy neutrino properties in the range of ~100 GeV - 3 TeV at the LHC collider in CERN (the FASER experiment). Search for new particles and exotic reactions. Estimation of neutrino interaction cross-sections.
Expected results upon completion of the project:
Determination of the neutrino mass ordering and the lepton CP-parity violation parameter in long-baseline acceleratorexperiments at a significance level of $\sim 3\sigma,$ precise measurement of the $\Delta m^{2}_{32}$ and ${\sin}{\theta}_{23}$ oscillation parameters. Joint analysis of neutrino experiment data. Search for new particles and exotic reactions. Measurement of neutrino interaction cross sectionsof all types for the energy range of 100 - 3000 GeV. Measurement of the $D_s$ meson production cross-section in proton-nucleuscollisions with subsequent decay to a tau lepton at 400 GeV/c. Refinement of the measurement of the tau neutrino flux fromaccelerators.
