Higgs-induced screening mechanisms in scalar-tensor theories (2023)
Journal Article

We consider the theory of a light conformally coupled scalar field, that is, one that is coupled directly to the Ricci scalar of the gravitational sector. This theory can be written equivalently as one of a light scalar that is coupled to the Standar... Read More about Higgs-induced screening mechanisms in scalar-tensor theories.

Spinning black holes with axion hair (2023)
Journal Article

In this work we construct and analyze non-perturbative stationary and axially-symmetric black hole solutions in general relativity coupled to an electromagnetic and an axion field. The axion field is coupled to the electromagnetic field, which leads... Read More about Spinning black holes with axion hair.

Invisible dilaton (2023)
Journal Article

We analyze the dynamics of a light scalar field responsible for the μ term of the Higgs potential and coupled to matter via the Higgs-portal mechanism. We find that this dilaton model is stable under radiative corrections induced by the standard mode... Read More about Invisible dilaton.
