| SISSA, Room 135 | h: 14:00 | Disformal Coupling, CMB Spectral Distortion and Distance Duality Relation |
| Giulia Gubitosi | Light scalar fields can naturally couple disformally to Standard Modelrnfields without giving rise to the unacceptably large fifth forces usually associated with light scalars. We show that these scalar fields can be studied and constrained through their interaction with photons, and focus particularly on changes to the Cosmic Microwave Background spectral distortions and violations of the distance duality relation. We then specialize our constraints to scalars which could play the role of axionic quintessence. | |
