Quantum Gravity Effects on Particle Properties |
Particle Properties > s.a. effects on photons;
modified lorentz symmetry; semiclassical
quantum gravity; spacetime foam.
* Idea: Quantum
spacetime fluctuations affect light and particle propagation, masses,
and possibly other properties, and some effects can be seen as a violation
of Lorentz symmetry; Relative corrections are typically of order
\((\lambda_{\rm fund}/\lambda)^2\); Consequences are expected to manifest
themselves mostly at Planck scales, and include baryon number violation in
black-hole formation and evaporation, CP and CPT violation (distinguished
from GUT effects), suppression of ultra-high energy scattering amplitudes.
* History: The first proposal
of modified dispersion relations may have been made in the 1971 paper by
Kirzhnits & Chechin about the absence of a GZK cutoff in the UHECR
spectrum.
