| « Parity violation features in inflationary models with vector fields » |
|
J.P. Beltran |
| Vector fields have been studied during last years and they has been considered as a well motivated source of statistical anisotropies and large scale anomalies. In this talk we will discuss some of the main features of those models, particularly, the models that include a coupling between a pseudo scalar and a massive vector field. We discuss particle production in these models and detail about how this kind of coupling allows for parity violating signals in the gravitational waves spectrum and in the scalar correlators. Finally, we comment on the thigh limits and challenges imposed by Planck 2015 over these models. |
