Measurement of CP violation at a Neutrino Factory

In this paper I discuss the prospects to observe a CP-odd phase in the leptonic sector, using the intense, pure two-flavour neutrino beams produced in a future neutrino facility, the so-called neutrino factory. The organization is as follows. Section 2 summarizes the state-of-the-art concerning neutrino oscillations. Section 3 describes the neutrino factory. The prospects to measure a CP-odd phase are discussed in section 4.
