Résumé
: In this
talk we will try to introduce the analysis
of cosmological observables as a suitable
arena for Relative Locality phenomenology.
One of the fundamental aspects of General
Relativity is that two different observers
on two different hypersurfaces describe
spacetime with two distinct sets of
coordinates, and, thus, they give
different coordinatizations of the same
spacetime. Relative Locality is a
relativistic theory that implements
systematic nonlocalities that can emerge
in many different approaches to the
problem of Quantum Gravity. In this
theory, locality is no longer absolute, as
codified in a novel way to mathematically
express translations between the two
hypersurfaces. We will give an explicit
example of signal analysis and related
phenomenology on cosmological observables,
with relative locality spacetime metric,
mathematically modelized on
kappa-Minkowski deformed spacetime
transformations. |
