摘要：

We study the potential of a Neutrino Factory (NF) to constrain the parameters of the (3 + 1)-scheme with a O(1) eV(2) largest mass square difference, considering two set-ups: a NF with 50 GeV (20 GeV) stored rations, with two detectors of the Hybrid-MIND type located at L = 3000 (4000),7500 km. We show that the best sensitivity to sterile neutrinos can be achieved through the v(mu) -> v(mu) and the v(mu) -> v(tau) channels which can constrain theta(34) <= 12 degrees (14 degrees) and theta(24) <= 7.5 degrees (8 degrees) with the 50 GeV (20 GeV) NF. We also study the CP-violation in this new context showing that the CP-asymmetries in the v(mu) -> v(tau) channel can give us the chance to sec a clear new CF-violation signal associated with the sterile neutrinos.
