Abstract:
Scientific goals of the DUNE project encompass a broad range of activities. These searches answers to neutrino oscillation studies combined with determining the neutrino mass ordering and to the measurements of CP violating phase, but in the same time new phenomena associated with theories beyond Standard Model are searched (the unification of the three fundamental forces, the matter - antimatter asymmetry of the Universe, proton decay or new particles as candidates for dark matter).
LAr experiments are particularly sensitive to proton decay modes, key mode of interest in this case is p→(K+)+anti(ν). Antineutrinos produced at nuclear reactors constitute a major source of background for searches of this decay channel.
Considering the fluxes of antineutrinos produces by nuclear plants existent in this moment on the terrestrial globe, we estimated their hypothetical contributions to background fluxes in DUNE experiment for proton decays.
