Upper Limit on the Diffuse Flux of Ultrahigh Energy Tau Neutrinos from the Pierre Auger Observatory (2008)

Allard, D., Armengaud, E., Aublin, J., Beau, T., Berat, C., Billoir, P., ...

The surface detector array of the Pierre Auger Observatory is sensitive to Earth-skimming tau-neutrinos $\nu_\tau$ that interact in the Earth's crust. Tau leptons from $\nu_\tau$ charged-current...

Constraints on mSUGRA through entropy and abundance criteria (2007)

Cabral-Rosetti, L. G., Mondragon, M., Nellen, L., Nunez, D., Sussman, R., Zavala, J.

We derive an expression for the entropy of a present dark matter halo described by a Navarro-Frenk-White modified model with a central core. The comparison of this entropy with the one of the halo at...

An upper limit of 16% (at 95% c.l.) is derived for the photon fraction in cosmic rays with energies greater than $10^{19}$ eV, based on observations of the depth of shower maximum performed with the...

We use the formalism of finite-temperature field theory to study the interactions of ultra-high energy (UHE) cosmic neutrinos with the background of relic neutrinos and to derive general expressions...

Observing muon decays in water Cherenkov detectors at the Pierre Auger Observatory (2005)

Allison, P., Arneodo, F., Bertou, X., Busca, N. G., Ghia, P. L., Medina, C., ...

Muons decaying in the water volume of a Cherenkov detector of the Pierre Auger Observatory provide a useful calibration point at low energy. Using the digitized waveform continuously recorded by the...

UHE neutrino damping in a thermal gas of relic neutrinos (2005)

D'Olivo, J. C., Nellen, L., Sahu, S., Van Elewyck, V.

We present a calculation of the damping of an ultra-energetic (UHE) cosmic neutrino travelling through the thermal gas of relic neutrinos, using the formalism of finite-temperature field theory. From...

Unfolding a degeneracy point of two unbound states: Crossings and anticrossings of energies and widths (2005)

Neutrino production through hadronic cascades in AGN accretion disks (1992)
