Future tests of non-standard neutrino interactions

We explore non-standard neutrino matter interactions, working as sub-leading effects in the standard mass oscillation framework. Both mechanisms working together, induce a magnifying fake CP violating effect in the presence of matter, which can be studied in a neutrino factory which is based on a muon storage ring. Considering the three neutrino scheme, assuming a 10 kt detector with 5 years of operation, a stored muon energy E_μ ≥ 20 GeV, 2 × 10²⁰ muon decays per year, and a baseline L ∼ 732 km, we show that it is possible to test non-standard flavor changing neutrino interactions down to the level of (10^-3 - 10^-2) G_F, in both v_μ → ντ/̄n_μ → ̄n_τ and ν_e → ν_τ/̄n_e → ̄n_τ modes.
