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

TL;DR

This paper clarifies that the argument in arXiv:1104.2019 does not address how to describe multi-particle states in models with deformed Lorentz symmetry, highlighting a gap in the original discussion.

Contribution

It provides a critique showing that the previous argument does not resolve the description of multi-particle states in deformed Lorentz-symmetry models.

Findings

The original argument does not address multi-particle state description.

Clarification of the limitations of the previous argument.

Highlights the need for further work on multi-particle states in these models.

Abstract

It is explained why the argument in arXiv:1104.2019 does not answer the question how to describe multi-particle states in models with a deformed Lorentz-symmetry in momentum space.
