Testing Fundamental Physics with High-Energy Cosmic Rays [PDF]

Nuovo Cim.C24:483-496,2001, 2000
Cosmic rays may provide opportunities for probing fundamental physics. For example, ultra-high-energy cosmic rays might originate from the decays of metastable heavy particles, and astrophysical gamma rays can be used to test models of quantum gravity. Both scenarios offer ways to avoid the GZK cut-off.

Cosmic-ray physics with IceCube [PDF]

Advances in Space Research, 2011
IceCube as a three-dimensional air-shower array covers an energy range of the cosmic-ray spectrum from below 1 PeV to approximately 1 EeV. This talk is a brief review of the function and goals of IceTop, the surface component of the IceCube neutrino ...

Chapter 4 Cosmic-Ray Physics * [PDF]

Chinese Physics C, 2022
Abstract In the first part of this Chapter the present state of knowledge from the observations of cosmic rays between 1013 and 1020 eV is summarized. This is not intended to be a complete review, but rather a broad overview of the relevant processes involving cosmic rays, including the astrophysical environments in which they take place.

Cosmic vortons and particle physics constraints [PDF]

Physical Review D, 1996
We investigate the cosmological consequences of particle physics theories that admit stable loops of superconducting cosmic string - {\it vortons}. General symmetry breaking schemes are considered, in which strings are formed at one energy scale and subsequently become superconducting in a secondary phase transition at what may be a considerably lower ...

Cosmic Ray Physics with ACORDE at LHC [PDF]

Journal of Physics: Conference Series, 2007
The use of large underground high-energy physics experiments, for comic ray studies, have been used, in the past, at CERN, in order to measure, precisely, the inclusive cosmic ray flux in the energy range from 2x10^10 - 2x10^12 eV.

Is cosmic speed-up due to new gravitational physics? [PDF]

, 2004
We show that cosmic acceleration can arise due to very tiny corrections to the usual gravitational action of general relativity, of the form ${R}^{\ensuremath{-}n}$ with $ng0.$ This model eliminates the need for a nonzero cosmological constant or any ...

Cosmic Physics: The High Energy Frontier

Journal of Physics G: Nuclear and Particle Physics, 2003
Cosmic rays have been observed up to energies $10^8$ times larger than those of the best particle accelerators. Studies of astrophysical particles (hadrons, neutrinos and photons) at their highest observed energies have implications for fundamental ...
