Mini-twistors and the Cotton Double Copy
Mariana Carrillo González, William T. Emond, Nathan Moynihan +2
The double copy relates quantities in gauge, gravity and related theories. A well-known procedure for relating exact classical solutions is the Weyl double copy in four spacetime d…
Phase Transitions in de Sitter: Quantum Corrections
José Eliel Camargo-Molina, Mariana Carrillo González, Arttu Rajantie
We investigate the decay rate of a false vacuum state in de Sitter space at high Hubble rates, using two methods: the Hawking-Moss instanton method which is fully quantum mechanica…
Cosmology and Signals of Light Pseudo-Dirac Dark Matter
Mariana Carrillo González, Natalia Toro
In this paper, we analyze the cosmological evolution, allowed parameter space, and observational prospects for a dark sector consisting of thermally produced pseudo-Dirac fermions…
Massive Double Copy in Three Spacetime Dimensions
Mariana Carrillo González, Arshia Momeni, Justinas Rumbutis
Recent explorations on how to construct a double copy of massive gauge fields have shown that, while any amplitude can be written in a form consistent with colour-kinematics dualit…
