Photon decayLorentz Invariant Violation(LIV)
Sidney Coleman, Sheldon L. Glashow, Phys.Rev. D59 (1999) 116008
Lorentz invariant is violated?
the energy calibration of AGASA is in doubt?
F.W. Stecker, S.T. Scully, Astropart.Phys. 23 (2005) 203-209
Thus, LIV can be constrained by the spectrum of UHECRs .Newest Experimental results
