چکیده
Abstract We calculate high-precision constraints on Natural Inflation relative to current observational from Planck 2018 + BICEP/Keck(BK15) Polarization BAO r and n S , including post-inflationary history of the universe. find that, for conventional dynamics, with a cosine potential is disfavored at greater than 95% confidence out by data. If we assume protracted reheating characterized w ?>1/3, can be brought into agreement constraints. However, bringing unmodified 68% region requires values T re below scale electroweak symmetry breaking. The addition SHOES prior Hubble Constant H 0 only worsens fit.

Multifield inflation after Planck: the case for nonminimal couplings.
Multifield models of inflation with nonminimal couplings are in excellent agreement with the recent results from Planck. Across a broad range of couplings and initial conditions, such models evolve along an effectively single-field attractor solution and predict values of the primordial spectral index and its running, the tensor-to-scalar ratio, and non-Gaussianities squarely in the observation...
متن کاملPlanck 2015 results - XX. Constraints on inflation
We present the implications for cosmic inflation of the Planck measurements of the cosmic microwave background (CMB) anisotropies in both temperature and polarization based on the full Planck survey, which includes more than twice the integration time of the nominal survey used for the 2013 release papers. The Planck full mission temperature data and a first release of polarization data on larg...
متن کاملNatural Inflation: status after WMAP 3-year data
Inflationary cosmology, a period of accelerated expansion in the early universe, is being tested by Cosmic Microwave Background measurements. Generic predictions of inflation have been shown to be correct, and in addition individual models are being tested. The model of Natural Inflation is examined in light of recent 3-year data from the Wilkinson Microwave Anisotropy Probe and shown to provid...
متن کاملNatural Supergravity Inflation
We identify a new mechanism in supergravity theories which leads to successful inflation without any need for fine tuning. The simplest model yields a spectrum of density fluctuations tilted away from scale-invariance and negligible gravitational waves. We demonstrate that this is consistent with the observed large-scale structure for a cold dark matter dominated, critical density universe. The...
متن کاملNatural Magnetogenesis from Inflation
We consider the gravitational generation of the massive Z boson field of the standard model, due to the natural breaking of its conformal invariance during inflation. The electroweak symmetry restoration at the end of inflation turns the almost scale-invariant superhorizon Z spectrum into a hypermagnetic field, which transforms into a regular magnetic field at the electroweak phase transition. ...
