Higher order terms in the inflation potential and the lower bound on the tensor to scalar ratio r

Journal Article Destri, C ; Vega, H.J. de, ; Observatoire de Paris, LERMA, Laboratoire Associe au CNRS UMR 8112, 61, Avenue de l'Observatoire, 75014 Paris ; ... - Annals of Physics (New York)

Research Highlights: > In Ginsburg-Landau (G-L) approach data favors new inflation over chaotic inflation. > n{sub s} and r fall inside a universal banana-shaped region in G-L new inflation. > The banana region for the observed value n{sub s}=0.964 implies 0.021<r<0.053. > Fermion condensate inflaton potential is a double well in the G-L class. - Abstract: The MCMC analysis of the CMB + LSS data in the context of the Ginsburg-Landau approach to inflation indicated that the fourth degree double-well inflaton potential in new inflation gives an excellent fit of the present CMB and LSS data.

Higgs inflation, reheating and gravitino production in no-scale Supersymmetric GUTs

Journal Article Ellis, John ; Theoretical Physics Department, CERN,CH-1211 Geneva 23 ; He, Hong-Jian ; ... - Journal of Cosmology and Astroparticle Physics

We extend our previous study of supersymmetric Higgs inflation in the context of no-scale supergravity and grand unification, to include models based on the flipped SU(5) and the Pati-Salam group. Like the previous SU(5) GUT model, these yield a class of inflation models whose inflation predictions interpolate between those of the quadratic chaotic inflation and Starobinsky-like inflation, while avoiding tension with proton decay limits. We further analyse the reheating process in these models, and derive the number of e-folds, which is independent of the reheating temperature. We derive the corresponding predictions for the scalar tilt and the tensor-to-scalar ratio inmore »« less

GUT-scale inflation with sizeable tensor modes

Journal Article Brümmer, Felix ; Domcke, Valerie ; Sanz, Verónica - Journal of Cosmology and Astroparticle Physics

A sizeable tensor-to-scalar ratio, such as recently claimed by BICEP2, would imply a scale of inflation at the typical scale of supersymmetric grand unification. This could be an accident, or strong support for supersymmetric theories. Models of F-term hybrid inflation naturally connect the GUT scale with the inflationary scale, but they also predict the tensor-to-scalar ratio to be unmeasurably small. In this work we analyze a general UV embedding of F-term hybrid inflation into a supergravity theory with a general Kähler potential. The CMB observables are generated during the early phase of inflation, at large inflaton values, where the potentialmore »« less

Upper bound for the supersymmetric tensor coupling of pion decay reexamined

Journal Article Ghilencea, D - Physical Review, D

We compute the supersymmetric pseudoscalar and tensor coupling of pion decay within the minimal supersymmetric standard model. The value of the tensor coupling is below previous limits computed through a different approach, and in disagreement with its experimental value. {copyright} {ital 1997} {ital The American Physical Society}
