On: Natural Inflation
We re-examine the original model of Natural inflation, in which the inflaton is a pseudo Nambu-Goldstone boson with potential of the form V (φ) = Λ[1 ± cos(φ/f)], in light of recent data. We find that the model is alive and well. Successful inflation as well as recent data from the Wilkinson Microwave Anisotropy probe require f > 0.6mPl (where mPl = 1.22 × 10 19 GeV) and Λ ∼ mGUT , scales which...
متن کاملNotes on natural inflation
In the so-called natural inflation, an axion-like inflaton is assumed to have a cosine-type periodic potential. This is not the case in a very simple model in which the axion-like inflaton is coupled to an SU(N) (or other) pure Yang-Mills, at least in the large N limit as pointed out by Witten. It has a multi-valued potential, which is effectively quadratic, i.e., there is only a mass term in t...
متن کاملRealizations of Hybrid Inflation in Supergravity with natural initial conditions
We present viable F-term realizations of the hybrid inflationary scenario in the context of supergravity addressing at the same time the well-known problems of the initial conditions and of the adequate suppression of the inflaton mass. An essential role in our construction is played by “decoupled” superheavy fields without superpotential acquiring large vevs due to D-terms associated with “ano...
متن کاملHybrid natural inflation from non Abelian discrete symmetry
A spontaneously broken global discrete symmetry may have pseudo Goldstone modes associated with the spontaneous breaking of the approximate continuous symmetry of the low dimension terms in the Lagrangian. These provide natural candidates for an inflaton that can generate slow roll inflation. We show that, in the case of a non Abelian discrete symmetry, the pseudo Goldstone modes readily couple...
متن کاملPerspective on completing natural inflation
*Correspondence: Bumseok Kyae, Department of Physics, Pusan National University, Busan 609-735, South Korea e-mail: [email protected] We present a perspective on the inflation paths in 2−,3−, . . . ,N−flation models based on the ultraviolet completion in heterotic string theory, where a number of grand unification scale axions are used. The number of non-Abelian gauge groups for a natural infla...
