The role of gauge fields during inflation

Author: Ricardo Zambujal


Abstract: Most of the early universe secrets are still left to be unravelled. The most vanilla-like ideas are in agreement with experiments and no significant deviations from standard predictions have been found.

There are however some reasons to believe that gauge fields, and in particular electromagnetic fields, might have had an important role in the early universe. These ideas also get some support from recent suggestive observations of magnetic fields in the largest scales of our observable universe.

In this talk I will present recent work done in the phenomenology and model building of gauge fields in the early universe, in particular during inflation.
