Phys. Rev. D 65, 103516 (2002) [8 pages]Loop quantum gravity corrections and cosmic ray decaysReceived 20 November 2001; published 10 May 2002 Loop quantum gravity effective theories are reviewed in the context of the observed Greizen-Zatsepin-Kuz’min limit anomaly and related processes. This is accomplished through a kinematical analysis of the modified threshold conditions for the decay reactions involved, arising from the theory. Especially interesting is the possibility of a helicity dependent violation of the limit, whose primary effect would be the observation of favored helicity states for highly energetic particles. © 2002 The American Physical Society URL:
