The precision and discovery potential of a neutrino factory based on muon storage rings is studied. For three-family neutrino oscillations, we analyse how to measure or severely constraint the angle �13, CP violation, MSW effects and the sign of the atmospheric mass differencem 2. We present a simple ana- lytical formula for the oscillation probabilities in matter, with all neutrino mass differences non-vanishing, which clarifies the subtleties involved in disentangling the unknown parameters. The appearance of "wrong-sign muons" at three ref- erence baselines is considered: 732 km, 3500 km, and 7332 km. We exploit the dependence of the signal on the neutrino energy, and include as well realistic background estimations and detection efficiencies. The optimal baseline turns out to be O(3000 km). Analyses combining the information from different base- lines are also presented.

Updated fit to three neutrino mixing: status of leptonic CP violation (2014, neutral): “This can be understood from the relevant νe appearance probability at T2K and MINOS, which, at the second order in the small parameters sin θ13 and α ≡ ∆m21/∆m31 and assuming a constant matter density, takes the form [70–72]: Pνμ→νe ≈ 4 sin θ13 sin θ23 sin ∆(1−A) (1−A)2 + α sin 2θ12 cos 2 θ23 sinA∆ ”
Status of three-neutrino oscillation parameters, circa 2013 (2013, neutral): “5π, since for sin δ ∼ −1 the CP-odd term in the νμ → νe appearance probability [35, 36] is maximized [17].”
Monte Carlo Study of Supernova Neutrino Spectra Formation (2002, background): “…if the neutrino mass hierarchy is normal or inverted will remain open and can be settled only by future precision measurements at dedicated long-baseline oscillation experiments (Barger et al. 2001, Cervera et al. 2000, Freund, Huber, & Lindner 2001) and/or the observation of a future galactic SN.”
