Analytic approximation to 5 dimensional black holes with one compact dimension
We study black hole solutions in R{sup 4}xS{sup 1} space, using an expansion to second order in the square of the ratio of the radius of the horizon, {mu}, and the circumference of the compactExpand

Higher mass scales and mass hierarchies
Abstract The impact of new interactions at very high energies on the spontaneous breaking of chiral symmetry in gauge field theories is studied. Described at low energies by higher dimensionExpand

Gravitationally Bound Bose Condensates with Rotation
We develop a self-consistent formulation of a slowly rotating, self-gravitating and dilute Bose-Einstein condensate (BEC) in the Newtonian approximation, with a view to astrophysical applications inExpand

Fractional spin via canonical quantization of the O(3) nonlinear sigma model
The 2 + 1 dimensional O(3) nonlinear sigma model with Hopf term of strength ϑ is canonically quantized. The solitons of topological charge Q are found to have spin equal to (ϑ/2π)Q2 modulo anExpand

Universality and the magnetic catalysis of chiral symmetry breaking
The hypothesis that the magnetic catalysis of chiral symmetry breaking is due to interactions of massless fermions in their lowest Landau level is examined in the context of chirally symmetric modelsExpand

Boson stars from self-interacting dark matter
A bstractWe study the possibility that self-interacting bosonic dark matter forms star-like objects. We study both the case of attractive and repulsive self-interactions, and we focus particularly inExpand

The Phase Structure of an SU(N) Gauge Theory with N f Flavors
We investigate the chiral phase transition in SU(N) gauge theories as the number of quark flavors, N{sub f}, is varied. We argue that the transition takes place at a large enough value of N{sub f} soExpand

The Lifetime of Axion Stars
We investigate the decay of condensates of scalars in a field theory defined by $V({\cal A})=m{}^2\,f{}^2\,[1-\cos({\cal A}\,/\,f)]$, where $m$ and $f$ are the mass and decay constant of the scalarExpand

NuTeV anomaly, lepton universality, and nonuniversal neutrino-gauge couplings
In previous studies we found that models with flavor-universal suppression of the neutrino-gauge couplings are compatible with NuTeV and Z-pole data. In this paper we expand our analysis to obtainExpand
