Cosmic particles with energies above 10^19 eV: a brief review of results

Abstract

Experimental results on ultra-high-energy cosmic rays are briefly reviewed and their interpretation is discussed. The results related to principal observables (arrival directions, energies and composition) of primary particles of extended air showers as well as particle-physics implications are addressed.
