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-mu greater than or equal to 20 GeV, 2 x 10(20) muon decays per year, and a baseline L similar to 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-mu --> nu(r)/(<(nu)over bar>)(mu) --> <(nu)over bar> and v(e) --> v(r) /<(nu)over bar>(e) --> <(nu)over bar> modes.
