Renormalization in theories with modified dispersion relations: Weak gravitational fields

Mostrar todas las versiones(3)

We consider a free quantum scalar field satisfying modified dispersion relations in curved spacetimes, within the framework of Einstein-Aether theory. Using a power counting analysis, we study the divergences in the adiabatic expansion of 〈 φ{symbol}2 〉 and 〈 Tμ ν 〉, working in the weak field approx...
