# Gamma ray burst delay times probe the geometry of momentum space

@article{Freidel2011GammaRB, title={Gamma ray burst delay times probe the geometry of momentum space}, author={Laurent Freidel and Lee Smolin}, journal={arXiv: High Energy Physics - Theory}, year={2011} }

We study the application of the recently proposed framework of relative locality to the problem of energy dependent delays of arrival times of photons that are produced simultaneously in distant events such as gamma ray bursts. Within this framework, possible modifications of special relativity are coded in the geometry of momentum space. The metric of momentum space codes modifications in the energy momentum relation, while the connection on momentum space describes possible non-linear…

We study the effects of relative locality dynamics in the case of the Snyder model. Several properties of this model differ from those of the widely studied models: for example, in the Snyder case…

### Planck-Scale Dual-Curvature Lensing and Spacetime Noncommutativity

- Physics
- 2017

It was recently realized that Planck-scale momentum-space curvature, which is expected in some approaches to the quantum-gravity problem, can produce dual-curvature lensing, a feature which mainly…

We propose that there is a regime of quantum gravity phenomena, for the case that the cosmological constant is small and positive, which concerns phenomena at temperatures below the deSitter…

We explore the many novel physical consequences of Born’s reciprocal Relativity theory in flat phase-space and to generalize the theory to the curved phase-space scenario. We provide with six…

Deformed relativistic kinematics have been considered as a way to capture residual effects of quantum gravity. It has been shown that they can be understood geometrically in terms of a curved…

### BORN'S PROPHECY LEAVES NO SPACE FOR QUANTUM GRAVITY

- Physics

I stress that spacetime is a redundant abstraction, since describing the physical content of all so-called "spacetime measurements" only requires timing (by a physical/material clock) of particle…

### A limit on the variation of the speed of light arising from quantum gravity effects

- PhysicsNature
- 2009

The detection of emission up to ∼31 GeV from the distant and short GRB, and no evidence for the violation of Lorentz invariance is found, which disfavour quantum-gravity theories in which the quantum nature of space–time on a very small scale linearly alters the speed of light.

We propose a deepening of the relativity principle according to which the invariant arena for nonquantum physics is a phase space rather than spacetime. Descriptions of particles propagating and…

There are two major alternatives for violating the (usual) Lorentz invariance at large (Planckian) energies or momenta—either not all inertial frames (in the Planck regime) are equivalent (e.g.,…
