Vacuum Energy and Standard Model Physics
G. L. Alberghi, A. Y. Kamenshchik, A. Tronconi +2
The conditions for the cancellation of one loop contributions to vacuum energy (both U.V. divergent and finite) coming from the Standard Model (SM) fields are examined. It is prove…
Cosmological Unparticle Correlators
G. L. Alberghi, A. Yu. Kamenshchik, A. Tronconi +2
We introduce and study an extension of the correlator of unparticle matter operators in a cosmological environment. Starting from FRW spaces we specialize to a de Sitter spacetime…
Inflation and the semiclassical dynamics of a conformal scalar field
G. L. Alberghi, C. Appignani, R. Casadio +2
We derive the semiclassical evolution of massless conformally coupled scalar matter in the de Sitter space-time from the Born-Oppenheimer reduction of the Wheeler-DeWitt equation.…
Vacuum energy and spectral function sum rules
A. Y. Kamenshchik, A. Tronconi, G. P. Vacca +1
We reformulate the problem of the cancellation of the ultraviolet divergencies of the vacuum energy, particularly important at the cosmological level, in terms of a saturation of s…
