The Interaction Structure and Cosmological Relevance of Mass Scales in String Motivated Supersymmetric Theories

Arjun Berera, Thomas W. Kephart

A string motivated, N=1 global supersymmetric, general Lagrangian is obtained that represents an inflaton interacting with the modes of a string. Focus is placed on the Lagrangian'…

Lower Energy Consequences of an Anomalous High-Energy Neutrino Cross-Section

Haim Goldberg, T. J. Weiler

A new strong-interaction has been postulated for neutrinos above ~10^{19} eV to explain the production of highest-energy cosmic ray events. We derive a dispersion relation relating…

A First Principles Warm Inflation Model that Solves the Cosmological Horizon/Flatness Problems

Arjun Berera, Marcelo Gleiser, Rudnei O. Ramos

A quantum field theory warm inflation model is presented that solves the horizon/flatness problems. The model obtains, from the elementary dynamics of particle physics, cosmologica…

GUT Cosmic Magnetic Fields in a Warm Inflationary Universe

Arjun Berera, Thomas W. Kephart, Stuart D. Wick

Sources of magnetic fields from grand unified theories are studied in the warm inflation regime. A ferromagnetic Savvidy vacuum scenario is presented that yields observationally in…

Inferred 4.4 eV Upper Limits on the Muon- and Tau-Neutrino Masses

V. Barger, T. J. Weiler, K. Whisnant

By combining experimental constraints from atmospheric and solar neutrino oscillations and the tritium beta decay endpoint, we infer upper limits of 4.4 eV on the and m…

Generalized Neutrino Mixing from the Atmospheric Anomaly

V. Barger, T. J. Weiler, K. Whisnant

We determine the neutrino mixing and mass parameters that are allowed by the Super-Kamiokande atmospheric neutrino data in a three-neutrino model with one mass-squared difference c…

Invariant Box-Parameterization of Neutrino Oscillations

Thomas J. Weiler, DJ Wagner

The model-independent "box" parameterization of neutrino oscillations is examined. The invariant boxes are the classical amplitudes of the individual oscillating terms. Being obser…

Bi-Maximal Mixing of Three Neutrinos

V. Barger, S. Pakvasa, T. J. Weiler +1

We show that if the solar and atmospheric data are both described by maximal vacuum oscillations at the relevant mass scales then there exists a unique mixing matrix for three neut…

Variations on Four-Neutrino Oscillations

V. Barger, S. Pakvasa, T. J. Weiler +1

We make a model-independent analysis of all available data that indicate neutrino oscillations. Using probability diagrams, we confirm that a mass spectrum with two nearly degenera…

Strong Dissipative Behavior in Quantum Field Theory

Arjun Berera, Marcelo Gleiser, Rudnei O. Ramos

We study under which conditions an overdamped regime can be attained in the dynamic evolution of a quantum field configuration. Using a real-time formulation of finite temperature…

Boxing with Neutrino Oscillations

DJ Wagner, Thomas J. Weiler

We develop a model-independent "box" parameterization of neutrino oscillations. Oscillation probabilities are linear in these new parameters, so measurements can straightforwardly…
