We determine the elements of the leptonic mixing matrix, without assuming unitarity, combining data from neutrino oscillation experiments and weak decays. To that end, we first develop a formalism for studying neutrino oscillations in vacuum and matter when the leptonic mixing matrix is not unitary. To be conservative, only three light neutrino species are(More)
For baselines of O(1000 km), the rich oscillation pattern at a Low-Energy Neutrino Factory (E ν = 0.5-≈ 3 GeV) provides unique performance with regard to sensitivity to CP violation and the determination of the neutrino mass hierarchy [1]. A unique neutrino detector is needed, however, in order to exploit this oscillation pattern. The Totally Active(More)
We study the measurement of the atmospheric neutrino oscillation parameters, θ 23 and ∆m 2 23 , at the ν µ disappearance channel at three conventional beam facilities, the SPL, T2K-phase I and NOνA. These two parameters have been shown to be of crucial importance in the measurement of two of the unknowns of the PMNS mixing matrix, θ 13 and the leptonic(More)
The Beta Beam CERN design is based on the present LHC injection complex and its physics reach is mainly limited by the maximum rigidity of the SPS. In fact, some of the scenarios for the machine upgrades of the LHC, particularly the construction of a fast cycling 1 TeV injector (" Super-SPS "), are very synergic with the construction of a higher γ Beta(More)
The study of the eightfold degeneracy at a neutrino complex that includes a standard β-Beam and a Super-Beam facility is presented for the first time in this paper. The scenario where the neutrinos are sent toward a Megaton water Cerenkov detector located at the Fréjus laboratory (baseline 130 Km) is exploited. The performance in terms of sensitivity for(More)
We discuss aidnogenesis 1 , i.e. the generation of a dark matter asymmetry, via new sphaleron processes associated to an extra non-abelian gauge symmetry common to both the visible and the dark sectors. Such a theory can naturally produce an abundance of asymmetric dark matter which is of the same size as the lepton and baryon asymmetries, as suggested by(More)
High density magnetized detectors are well suited to exploit the outstanding purity and intensities of novel neutrino sources like Neutrino Factories and Beta Beams. They can also provide independent measurements of leptonic mixing parameters through the observation of atmospheric muon-neutrinos. In this paper, we discuss the combination of these(More)
We study the potential of general quantum operations, Trace-Preserving Completely-Positive Maps (TPCPs), as encoding and decoding mechanisms in quantum authentication protocols. The study shows that these general operations do not offer significant advantage over unitary encodings. We also propose a practical authentication protocol based on the use of two(More)
