Dark Matter searches in Dwarf Galaxies with the Southern Wide-field Gamma-ray Observatory

Micael Andrade, Aion Viana

Dark matter is thought to make up most of the matter density of the Universe, yet its true nature remains uncertain. Among dark matter theories, Weakly Interacting Massive Particle…

HAWC measurements of the energy spectra of cosmic ray protons, helium and heavy nuclei in the TeV range

Juan Carlos Arteaga-Velázquez

Current knowledge of the relative abundances and the energy spectra of the elemental mass groups of cosmic rays in the TeV - PeV interval is uncertain. This situation prev…

Atmospheric effects on extensive air showers observed with the Surface Detector of the Pierre Auger Observatory

The Pierre Auger Collaboration

Atmospheric parameters, such as pressure (P), temperature (T) and density, affect the development of extensive air showers initiated by energetic cosmic rays. We have studied the i…

Limit on the diffuse flux of ultra-high energy tau neutrinos with the surface detector of the Pierre Auger Observatory

The Pierre Auger Collaboration

Data collected at the Pierre Auger Observatory are used to establish an upper limit on the diffuse flux of tau neutrinos in the cosmic radiation. Earth-skimming may interact…

Observation of the suppression of the flux of cosmic rays above 4x10^19eV

The Pierre Auger Collaboration

The energy spectrum of cosmic rays above 2.5x10^18eV, derived from 20,000 events recorded at the Pierre Auger Observatory, is described. The spectral index gamma of the flux, J ~ E…

First Observation of the Cabibbo-suppressed Decays Xi_c+ -> Sigma+ pi- pi+ and Xi_c+ -> Sigma- pi+ pi+ and Measurement of their Branching Ratios

SELEX Collaboration, E. Vazquez-Jauregui, J. Engelfried

We report the first observation of two Cabibbo-suppressed decay modes, Xi_c+ -> Sigma+ pi- pi+ and Xi_c+ -> Sigma- pi+ pi+. We observe 59+/-14 over a background of 87, and 22+/-8 o…
