Planck-Scale Soccer-Ball Problem: A Case of Mistaken Identity

Concerns that a nonlinear law of addition of momenta might inevitably produce a pathological description of the total momentum of a macroscopic body are unjustified, finding that they are rooted in failure to appreciate the differences between two roles for laws composition of momentum in physics.

Snyder Momentum Space in Relative Locality

The standard approaches of phenomenology of quantum gravity have usually explicitly violated Lorentz invariance, either in the dispersion relation or in the addition rule for momenta. We investigate

Quantum fields in curved spacetime, semiclassical gravity, quantum gravity phenomenology, and analogue models: parallel session D4

The talks given in parallel session D4 are summarized.



Comment on arXiv:1104.2019,"Relative locality and the soccer ball problem,"by Amelino-Camelia et al

It is explained why the argument in arXiv:1104.2019 does not answer the question how to describe multi-particle states in model s with a deformed Lorentz-symmetry in momentum space. In [1], the

Principle of relative locality

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

Relative locality and the soccer ball problem

We consider the behavior of macroscopic bodies within the framework of relative locality [G. Amelino-Camelia, L. Freidel, J. Kowalski-Glikman, and L. Smolin, arXiv:1101.0931]. This is a recent
