The Metaplectic Group, the Symplectic Spinor and the Gouy Phase

M. Fernandes, B. J. Hiley

In this paper we discuss a simplified approach to the symplectic Clifford algebra, the symplectic Clifford group and the symplectic spinor by first extending the Heisenberg algebra…

Searches for Large-Scale Anisotropy in the Arrival Directions of Cosmic Rays Detected above Energy of eV at the Pierre Auger Observatory and the Telescope Array

The Pierre Auger, Telescope Array Collaborations, : +605

Spherical harmonic moments are well-suited for capturing anisotropy at any scale in the flux of cosmic rays. An unambiguous measurement of the full set of spherical harmonic coeffi…

Reconstruction of inclined air showers detected with the Pierre Auger Observatory

The Pierre Auger Collaboration, A. Aab, P. Abreu +485

We describe the method devised to reconstruct inclined cosmic-ray air showers with zenith angles greater than detected with the surface array of the Pierre Auger Observa…
