Self-Dual Cosmology
Mariana Carrillo González, Arthur Lipstein, Silvia Nagy
We construct cosmological spacetimes with a self-dual Weyl tensor whose dynamics are described by conformally coupled scalars with only cubic self-interactions. Similar to the prev…
Neutrino-Assisted Early Dark Energy is a Natural Resolution of the Hubble Tension
Mariana Carrillo González, Qiuyue Liang, Jeremy Sakstein +1
It has very recently been claimed that the neutrino-assisted early dark energy model -- a promising resolution of the Hubble tension that can ameliorate the theoretical fine-tuning…
Massive Double Copy in the High-Energy Limit
Mariana Carrillo González, Arshia Momeni, Justinas Rumbutis
The exploration of the massive double copy is still in its infancy, and only a few examples in limited contexts are known. In this paper, we analyze the newly discovered double cop…
Solitons in generalized galileon theories
Mariana Carrillo-Gonzalez, Ali Masoumi, Adam R. Solomon +1
We consider the existence and stability of solitons in generalized galileons, scalar field theories with higher-derivative interactions but second-order equations of motion. It has…
Testing Hybrid Natural Inflation with BICEP2
Mariana Carrillo-Gonzalez, Gabriel German, Alfredo Herrera-Aguilar +2
We analyse Hybrid Natural Inflation in view of the recent results for the tensor index reported by BICEP2. We find that it predicts a large running of the scalar spectrum which is…
