Search for signatures of magnetically-induced alignment in the arrival directions measured by the Pierre Auger Observatory
The Pierre Auger Collaboration, P. Abreu, M. Aglietta +496
We present the results of an analysis of data recorded at the Pierre Auger Observatory in which we search for groups of directionally-aligned events (or `multiplets') which exhibit…
Ultrahigh energy neutrinos with a mediterranean neutrino telescope
E. Borriello, G. Miele, O. Pisanti
A study of the ultra high energy neutrino detection performances of a km^3 Neutrino Telescope sitting at the three proposed sites for "ANTARES", "NEMO" and "NESTOR" in the Mediterr…
High Energy Neutrinos with a Mediterranean Neutrino Telescope
E. Borriello, A. Cuoco, G. Mangano +4
The high energy neutrino detection by a km^3 Neutrino Telescope placed in the Mediterranean sea provides a unique tool to both determine the diffuse astrophysical neutrino flux and…
Non equilibrium spectra of degenerate relic neutrinos
S. Esposito, G. Miele, S. Pastor +2
We calculate the exact kinetic evolution of cosmic neutrinos until complete decoupling, in the case when a large neutrino asymmetry exists. While not excluded by present observatio…
A potential test of the CP properties and Majorana nature of neutrinos
S. Pastor, J. Segura, V. B. Semikoz +1
The scattering of solar neutrinos on electrons may reveal their CP properties, which are particularly sensitive to their Majorana nature. The cross section is sensitive to the neut…
Unstable massive tau-neutrinos and primordial nucleosynthesis
A. D. Dolgov, S. H. Hansen, S. Pastor +1
The impact of unstable Majorana tau neutrinos on primordial nucleosynthesis is considered. The mass and lifetime of nu_tau are taken in the intervals 0.1-20 MeV and 0.001-400 sec r…
Low-energy solar anti-neutrinos
V. B. Semikoz, S. Pastor, J. W. F. Valle
If neutrino conversions within the Sun result in partial polarization of initial solar neutrino fluxes, then a new opportunity arises to observe the anti-ν_e's in future neutrino e…
Neutrino magnetic moments and low-energy solar neutrino-electron scattering experiments
S. Pastor, J. Segura, V. B. Semikoz +1
The scattering of solar neutrinos on electrons is sensitive to the neutrino magnetic moments through an interference of electromagnetic and weak amplitudes in the cross section. We…
Low-energy Anti-neutrinos from the Sun
S. Pastor, V. B. Semikoz, J. W. F. Valle
We consider the sensitivity of future neutrino experiments in the low energy region, such as BOREXINO or HELLAZ, to a solar electron antineutrino signal. We show that, if neutrino…
Primordial Nucleosynthesis, Majorons and Heavy Tau Neutrinos
A. D. Dolgov, S. Pastor, J. C. Romao +1
We determine the restrictions imposed by primordial nucleosynthesis upon a heavy tau neutrino, in the presence of nu-tau annihilations into Majorons, as expected in a wide class of…
Nucleosynthesis constraints on heavy tau-neutrino in the presence of annihilations to majorons
S. Pastor
We show that in the presence of sufficiently strong annihilations to majorons, primordial nucleosynthesis constraints can not rule out any values of the mass up the pre…
An improved cosmological bound on the tau-neutrino mass
A. D. Dolgov, S. Pastor, J. W. F. Valle
We consider the influence of non-equilibrium electronic neutrinos (and anti-neutrinos) on the neutron-to-proton ratio. These neutrinos would come from massive annihilations $…
Bounds on Neutrino Transition Magnetic Moments in Random Magnetic Fields
V. B. Semikoz, S. Pastor, J. W. F. Valle
We consider the conversions of active to sterile Majorana neutrinos and , due to neutrino transition magnetic moments in the presence of random magnetic fields (r.m.…
New Supernova Constraints on active-sterile neutrino conversions
V. Semikoz, J. W. F. Valle
We consider active-sterile neutrino conversions in a supernova in the presence of random magnetic field domains. For large enough fields the magnetization of the medium may enhance…
