| Popis: | Experiments measuring the parameters of active neutrino oscillations can also search for the sterile neutrinos in a part of sterile neutrino parameter space. In this paper, we analyze the prospects for the sterile neutrino search in the upcoming experiment DUNE for the sterile neutrinos with masses at GeV scale. As it relies on the still-undecided design of the Near Detector, we provide the expected number of the sterile neutrino decays in the Near Detector volume. Our most optimistic predictions show that the corresponding limit on mixing can be approximately of the same order as the previous estimates made for the LBNE. We present our results as separate plots for the sterile neutrino mixing with electron, muon and tau neutrinos. Generally, DUNE has good prospects to probe large region of the previously unavailable part of the parameter space before the new projects (like SHiP) join the searches.
