Non-minimal (self-)running inflation: metric vs. Palatini formulation
نویسندگان
چکیده
A bstract We consider a model of quartic inflation where the inflaton is coupled non-minimally to gravity and self-induced radiative corrections its effective potential are dominant. perform comparative analysis considering two different formulations gravity, metric or Palatini, choices for renormalization scale, widely known as prescription I II. Moreover we comment on eventual compatibility results with final data release Planck mission.

Inflation with Non-Minimal Coupling: Metric vs. Palatini Formulations
We analyze non-minimally coupled scalar field theories in metric (second-order) and Palatini (first-order) formalisms in a comparative fashion. After contrasting them in a general setup, we specialize to inflation and find that the two formalisms differ in their predictions for various cosmological parameters. The main reason is that dependencies on the non-minimal coupling parameter are differ...
متن کاملPalatini versus metric formulation in higher-curvature gravity
We compare the metric and the Palatini formalism to obtain the Einstein equations in the presence of higher-order curvature corrections that consist of contractions of the Riemann tensor, but not of its derivatives. We find that, with the exception of standard Einsteingravity, the two formalisms are not equivalent, but that the Palatini formalism is contained within the metric formalism, in the...
متن کاملHybrid Metric-Palatini Gravity
Recently, the phenomenology of f(R) gravity has been scrutinized. This scrutiny has been motivated by the possibility to account for the self-accelerated cosmic expansion without invoking dark energy sources. Besides, this kind of modified gravity is capable of addressing the dynamics of several self-gravitating systems alternatively to the presence of dark matter. It has been established that ...
متن کاملAsymptotically Safe Non-Minimal Inflation
We study the constraints imposed by the requirement of Asymptotic Safety on a class of inflationary models with an inflaton field non-minimally coupled to the Ricci scalar. The critical surface in the space of theories is determined by the improved renormalization group flow which takes into account quantum corrections beyond the one loop approximation. The combination of constraints deriving f...
متن کاملInflation by non-minimal coupling
Inflationary scenarios based on simple non-minimal coupling aφ2R and its generalizations are studied. First, generalizing the form of non-minimal coupling to K(φ)R with an arbitrary function K, we show that the flat potential still is obtainable when V (φ)/K2(φ) is asymptotically constant. Very interestingly, if the ratio of the dimensionless quartic coupling(λ) of the inflaton field and the no...
