Reevaluation of the Prospect of Observing Neutrinos from Galactic Sources in the Light of Recent Results in Gamma Ray and Neutrino Astronomy
M. C. Gonzalez-Garcia, F. Halzen, V. Niro
In light of the recent IceCube evidence for a flux of extraterrestrial neutrinos, we revisit the prospect of observing the sources of the Galactic cosmic rays. In particular, we up…
GRBs on probation: testing the UHE CR paradigm with IceCube
M. Ahlers, M. C. Gonzalez-Garcia, F. Halzen
Gamma ray burst (GRB) fireballs provide one of very few astrophysical environments where one can contemplate the acceleration of cosmic rays to energies that exceed 10^20 eV. The a…
GZK Neutrinos after the Fermi-LAT Diffuse Photon Flux Measurement
M. Ahlers, L. A. Anchordoqui, M. C. Gonzalez-Garcia +2
Cosmogenic neutrinos originate from photo-hadronic interactions of cosmic ray protons with the cosmic microwave background (CMB). The neutrino production rate can be constrained th…
Quantum Decoherence of Photons in the Presence of Hidden U(1)s
M. Ahlers, L. A. Anchordoqui, M. C. Gonzalez-Garcia
Many extensions of the standard model predict the existence of hidden sectors that may contain unbroken abelian gauge groups. We argue that in the presence of quantum decoherence p…
Identifying Galactic PeVatrons with Neutrinos
M. C. Gonzalez-Garcia, Francis Halzen, Soumya Mohapatra
We perform a realistic evaluation of the potential of IceCube, a kilometer-scale neutrino detector under construction at the South Pole, to detect neutrinos in the direction of the…
Probing Planck scale physics with IceCube
Luis A. Anchordoqui, Haim Goldberg, M. C. Gonzalez-Garcia +4
Neutrino oscillations can be affected by decoherence induced e.g. by Planck scale suppressed interactions with the space-time foam predicted in some approaches to quantum gravity.…
Zenith angle distributions at Super-Kamiokande and SNO and the solution of the solar neutrino problem
M. C. Gonzalez-Garcia, C. Peña-Garay, A. Yu. Smirnov
We have performed a detailed study of the zenith angle dependence of the regeneration factor and distributions of events at SNO and SK for different solutions of the solar neutrino…
Four-Neutrino Oscillations at SNO
M. C. Gonzalez-Garcia, C. Peña-Garay
We discuss the potential of SNO to constraint the four-neutrino mixing schemes favoured by the results of all neutrino oscillations experiments. These schemes allow simultaneous tr…
Global three-neutrino oscillation analysis of neutrino data
M. C. Gonzalez-Garcia, M. Maltoni, C. Peña-Garay +1
A global analysis of the solar, atmospheric and reactor neutrino data is presented in terms of three-neutrino oscillations. We include the most recent solar neutrino rates of Homes…
Phenomenology of Maximal and Near-Maximal Lepton Mixing
M. C. Gonzalez-Garcia, C. Peña-Garay, Y. Nir +1
We study the phenomenological consequences of maximal and near-maximal mixing of the electron neutrino with other (=tau and/or muon) neutrinos. We describe the deviations from m…

Seasonal Dependence in the Solar Neutrino Flux
P. C. de Holanda, C. Peña-Garay, M. C. Gonzalez-Garcia +1
MSW solutions of the solar neutrino problem predict a seasonal dependence of the zenith angle distribution of the event rates, due to the non-zero latitude at the Super-Kamiokande…
