Breaking Diffeomorphism Invariance and Tests for the Emergence of Gravity
Mohamed M. Anber, Ufuk Aydemir, John F. Donoghue
If general relativity is an emergent phenomenon, there may be small violations of diffeomorphism invariance. We propose a phenomenology of perturbatively small violations of genera…
Naturally inflating on steep potentials through electromagnetic dissipation
Mohamed M. Anber, Lorenzo Sorbo
In models of natural inflation, the inflaton is an axion-like particle. Unfortunately, axion potentials in UV-complete theories appear to be too steep to drive inflation. We show t…
Comments on the Minimal Vectorial Standard Model
Mohamed M. Anber, Ufuk Aydemir, John F. Donoghue +1
We explore the available parameter space of the minimal vectorial Standard Model. In this theory, the gauge currents are initially vectorial but the Higgs sector produces chiral ma…
