Constraints on Natural Inflation from Cosmic Microwave
We study constraints on the natural inflation model from the cosmic microwave background radiation (CMBR). Inflaton φ for the natural inflation has a potential of the form V = Λ4[1− cos(φ/ √ 2fφ)], which is parametrized by two parameters fφ and Λ. Various cosmological quantities, like the primordial curvature perturbation and the CMBR anisotropy, are determined as functions of these two paramet...
متن کاملCosmological constraints from the cosmic microwave background
Using an approximate likelihood method adapted to band–power estimates, we analyze the ensemble of first generation cosmic microwave background anisotropy experiments to deduce constraints over a six–dimensional parameter space describing Inflation–generated adiabatic, scalar fluctuations. The basic preferences of simple Inflation scenarios are consistent with the data set: flat geometries (Ωto...
متن کاملCosmic microwave background bispectrum and inflation
We derive an expression for the non-Gaussian cosmic microwave background ~CMB! statistic I l 3 defined recently by Ferreira, Magueijo, and Górski in terms of the slow-roll-inflation parameters e and h . This result shows that a nonzero value of I l 3 in COBE would rule out single-field slow-roll inflation. A sharp change in the slope of the inflaton potential could increase the predicted value ...
متن کاملCosmic microwave background probes models of inflation.
Inflation creates both scalar (density) and tensor (gravity wave) metric perturbations. We find that the tensor mode contribution to the CMB anisotropy on large-angular scales can only exceed that of the scalar mode in models where the spectrum of perturbations deviates significantly from scale invariance (e.g., extended and power-law inflation models and extreme versions of chaotic inflation)....
متن کاملThe Cosmic Microwave Background Bispectrum and Inflation
We derive an expression for the non-Gaussian cosmic-microwave-background (CMB) statistic I3 l defined recently by Ferreira, Magueijo, and Górski in terms of the slow-roll-inflation parameters ǫ and η. This result shows that a nonzero value of I3 l in COBE would rule out single-field slow-roll inflation. A sharp change in the slope of the inflaton potential could increase the predicted value of ...
