Pauli-Zeldovich cancellation of the vacuum energy divergences, auxiliary fields and supersymmetry

A. Yu. Kamenshchik, A. A. Starobinsky, A. Tronconi +2

We have considered the Pauli-Zeldovich mechanism for the cancellation of the ultraviolet divergences in vacuum energy. This mechanism arises because bosons and fermions give contri…

Inflationary quasi-scale invariant attractors

Massimiliano Rinaldi, Luciano Vanzo, Sergio Zerbini +1

In a series of recent papers Kallosh, Linde, and collaborators have provided a unified description of single-field inflation with several types of potentials, ranging from power la…

Integrable cosmological models with non-minimally coupled scalar fields

A. Yu. Kamenshchik, E. O. Pozdeeva, A. Tronconi +2

We obtain general solutions for some flat Friedmann universes filled with a scalar field in induced gravity models and models including the Hilbert-Einstein curvature term plus a s…

Stochastic growth of quantum fluctuations during inflation

F. Finelli, G. Marozzi, A. A. Starobinsky +2

The standard field-theoretical approach to the slow-roll inflation is introduced. We then show as, in order to calculate the mean square of the canonical gauge invariant quantum fl…

Stochastic growth of quantum fluctuations during slow-roll inflation

F. Finelli, G. Marozzi, A. A. Starobinsky +2

We compute the growth of the mean square of quantum fluctuations of test fields with small effective mass during a slowly changing, nearly de Sitter stage which took place in diffe…

Generation of fluctuations during inflation: comparison of stochastic and field-theoretic approaches

F. Finelli, G. Marozzi, A. A. Starobinsky +2

We prove that the stochastic and standard field-theoretical approaches produce exactly the same results for the amount of light massive scalar field fluctuations generated during i…

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…

The Impact of Ultraviolet Regularization on the Spectrum of Curvature Perturbations During Inflation

F. Finelli, G. Marozzi, G. P. Vacca +1

Inflationary predictions based on the linear theory of cosmological perturbations are related to the two point function of a (second quantized) real scalar free field during the ac…
