We make an improved analysis on the flow of neutrinos originating from WIMP annihilations inside the Sun and the Earth. We treat both neutrino interaction and oscillation effects in a consistent framework. Our numerical simulations are performed in an event based setting, which is useful for both theoretical studies and for creating neutrino telescope Monte(More)
We discuss the interplay of non-standard interactions between neutrinos and charged fermions and their impact on the currently running OPERA experiment. We show that, due to the relatively short distance between CERN and the Gran Sasso laboratory, the neutrino oscillation probabilities can be expanded in the baseline length. This results in a rather simple(More)
Jacobo López-Pavón Instituto de F́ısica Teórica UAM/CSIC, Universidad Autónoma de Madrid, 28049 Cantoblanco, Madrid, Spain Abstract A low energy non-unitary leptonic mixing matrix is a generic feature of many extensions of the Standard Model. In such a case, the task of future precision neutrino oscillation experiments is more ambitious than measuring the(More)
The relatively large measured value of θ13 has opened various possiblities to determine the neutrino mass ordering, among them using PINGU, the low-energy extention of the IceCube neutrino telescope, to observe matter effects in atmospheric neutrinos, or a high statistics measurment of the neutrino energy spectrum at a reactor neutrino experiment with a(More)
We discuss aidnogenesis, 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 the(More)
We investigate non-standard Hamiltonian effects on neutrino oscillations, which are effective additional contributions to the vacuum or matter Hamiltonian. Since these effects can enter in either flavor or mass basis, we develop an understanding of the difference between these bases representing the underlying theoretical model. In particular, the simplest(More)
We discuss the phenomenology of damping signatures in the neutrino oscillation probabilities, where either the oscillating terms or the probabilities can be damped. This approach is a possibility for tests of non-oscillation effects in future neutrino oscillation experiments, where we mainly focus on reactor and long-baseline experiments. We extensively(More)
We investigate the effects of a non-zero leptonic mixing angle θ13 on the solar neutrino day-night asymmetry. Using a constant matter density profile for the Earth and well-motivated approximations, we derive analytical expressions for the νe survival probabilities for solar neutrinos arriving directly at the detector and for solar neutrinos which have(More)
