Journal ArticleDOI
Quantum gravity corrections to neutrino propagation
TL;DR: Neutrino bursts accompanying gamma ray bursts that have traveled cosmological distances L are considered and a dependence L(-1)(os) approximately &pmacr;(2)l(P) is found for a two-flavor neutrino oscillation length.
Journal ArticleDOI
Loop quantum gravity and light propagation
TL;DR: In this paper, a coarse-grained approximation for the Einstein-Maxwell theory that yields effective Maxwell equations in flat spacetime comprising Planck scale corrections is presented. But it is only in the magnetic sector which is briefly discussed.
Journal ArticleDOI
Quantum gravity and spin-1/2 particle effective dynamics
TL;DR: In this paper, an effective dynamics of spin-1/2 particles is obtained within the framework of loop quantum gravity by exploiting the generic properties that a semiclassical state of the compound system fermions plus gravity should have.
Journal ArticleDOI
Quantum gravity and Lorentz invariance violation in the standard model.
TL;DR: It is shown that the standard model itself contains tiny Lorentz invariance violation terms coming from QG, and all terms depend on one arbitrary parameter alpha that sets the scale of QG effects.
Journal ArticleDOI
Algebra of Higher Antibrackets
TL;DR: In this article, a simplified description of higher antibrackets, generalizations of the conventional antibracket of the Batalin-Vilkovisky formalism, is presented.
