The LHC as an Axion-Photon Collider
Sergio Barbosa, Matheus Coelho, Sylvain Fichet +2
Assuming the existence of an axion-like particle (ALP), beams of relativistic particles emit fluxes of quasi-real ALPs, analogous to the photon fluxes described by Weizsäcker-Willi…
On The Black Hole Weak Gravity Conjecture and Extremality in the Strong-Field Regime
Sergio Barbosa, Sylvain Fichet, Lucas de Souza
We point out that the Weak Gravity Conjecture (WGC) implies that sufficiently small extremal black holes are necessarily in the strong-field regime of electrodynamics, and therefor…
Running Love Numbers and the Effective Field Theory of Gravity
Sergio Barbosa, Philippe Brax, Sylvain Fichet +1
Massive states produce higher derivative corrections to Einstein gravity in the infrared, which are encoded into operators of the Effective Field Theory (EFT) of gravity. These EFT…
