Resurrection of large lepton number asymmetries from neutrino flavor oscillations
Gabriela Barenboim, William H. Kinney, Wan-Il Park
We numerically solve the evolution equations of neutrino three-flavor density matrices, and show that, even if neutrino oscillations mix neutrino flavors, large lepton number asymm…
Natural Inflation: the status after WMAP 3-year data
Katherine Freese, William H. Kinney, Christopher Savage
The model of Natural Inflation is examined in light of recent 3-year data from the Wilkinson Microwave Anisotropy Probe and shown to provide a good fit. The inflaton potential is n…
Natural Inflation: status after WMAP 3-year data
Christopher Savage, Katherine Freese, William H. Kinney
The model of Natural Inflation is examined in light of recent 3-year data from the Wilkinson Microwave Anisotropy Probe and shown to provide a good fit. The inflaton potential is n…
WMAPping inflationary physics
William H. Kinney, Edward W. Kolb, Alessandro Melchiorri +1
We extract parameters relevant for distinguishing among single-field inflation models from the Wilkinson Microwave Anisotropy Probe (WMAP) data set, and from a combination of the W…
Back reaction of a long range force on a Friedmann-Robertson-Walker background
Martina Brisudova, William H. Kinney
It is possible that there may exist long-range forces in addition to gravity. In this paper we construct a simple model for such a force based on exchange of a massless scalar fiel…
Measuring the cosmological lepton asymmetry through the CMB anisotropy
William H. Kinney, Antonio Riotto
A large lepton asymmetry in the Universe is still a viable possibility and leads to many interesting phenomena such as gauge symmetry nonrestoration at high temperature. We show th…
A Signature of Inflation from Dynamical Supersymmetry Breaking
William H. Kinney, Antonio Riotto
In models of cosmological inflation motivated by dynamical supersymmetry breaking, the potential driving inflation may be characterized by inverse powers of a scalar field. These m…
Dynamical Supersymmetric Inflation
William H. Kinney, Antonio Riotto
We propose a new class of inflationary models in which the scalar field potential governing inflation is generated by the same non-perturbative gauge dynamics that may lead to supe…
A Hamilton-Jacobi approach to non-slow-roll inflation
William H. Kinney
I describe a general approach to characterizing cosmological inflation outside the standard slow-roll approximation, based on the Hamilton-Jacobi formulation of scalar field dynami…
Inflation at Low Scales: General Analysis and a Detailed Model
William H. Kinney, K. T. Mahanthappa
Models of inflationary cosmology based on spontaneous symmetry breaking typically suffer from the shortcoming that the symmetry breaking scale is driven to nearly the Planck scale…
Inflation From Symmetry Breaking Below the Planck Scale
William H. Kinney, K. T. Mahanthappa
We investigate general scalar field potentials \hbox{} for inflationary cosmology arising from spontaneous symmetry breaking. We find that potentials which are dom…
Natural Inflation From Fermion Loops
William H. Kinney, K. T. Mahanthappa
``Natural'' inflationary theories are a class of models in which inflation is driven by a pseudo-Nambu-Goldstone boson. In this paper we consider two models, one old and one new, i…
