A Mass Matrix for Atmospheric, Solar, and LSND Neutrino Oscillations
James M. Gelb, S. P. Rosen
We construct a mass matrix for the four neutrino flavors, three active and one sterile, needed to fit oscillations in all three neutrino experiments: atmospheric, solar, and LSND,…
Comment on the broadening of the Be neutrino line in vacuum oscillation solutions of the solar neutrino
James M. Gelb, S. P. Rosen
We consider the effect of thermal broadening of the Be neutrino on vacuum oscillation solutions of the solar neutrino problem and analyze the conditions under which the electro…
Another Look at Just-So Solar Neutrino Oscillations
James M. Gelb, S. P. Rosen
We take another look at ``Just-So'' solar neutrino oscillations, characterizing them by the energy at which the distance-varying angle is , instead of the usual $Δm^…
Relativistic electrons in a rotating spherical magnetic dipole: localized three-dimensional states
James M. Gelb, Kaundinya S. Gopinath, Dallas C. Kennedy
Paralleling a previous paper, we examine single- and many-body states of relativistic electrons in an intense, rotating magnetic dipole field. Single-body orbitals are derived semi…
Relativistic charged particle in the dipole-sphere configuration. II. General tilted surface orbits
Kaundinya S. Gopinath, Dallas C. Kennedy, James M. Gelb
The original version of this paper has been withdrawn by the authors and merged with the revised version of astro-ph/9702014.
Relativistic electrons on a rotating spherical magnetic dipole: surface orbitals
James M. Gelb, Kaundinya S. Gopinath, Dallas C. Kennedy
The semiclassical orbitals of a relativistic electron on a rotating sphere threaded by an intense magnetic dipole field are examined. Several physically distinct regimes emerge, de…
Searching for the MSW Enhancement
James M. Gelb, Waikwok Kwong, S. P. Rosen
We point out that the length scale associated with the MSW effect is the radius of the Earth. Therefore to verify matter enhancement of neutrino oscillations, it will be necessary…
Cold Dark Matter II: Spatial and Velocity Statistics
James M. Gelb, Edmund Bertschinger
We examine high-resolution gravitational N-body simulations of the cold dark matter (CDM) model in order to determine whether there is any normalization of the initial densit…
Cold Dark Matter I: The Formation of Dark Halos
James M. Gelb, Edmund Bertschinger
We use numerical simulations of critically-closed cold dark matter (CDM) models to study the effects of numerical resolution on observable quantities. We study simulations with up…
Evolution of One-Point Distributions from Gaussian Initial Fluctuations
Lev Kofman, Edmund Bertschinger, James M. Gelb +2
We study the quasilinear evolution of the one-point probability density functions (PDFs) of the smoothed density and velocity fields in a cosmological gravitating system beginning…
Large- and Small-Scale Constraints on Power Spectra in Universes
James. M. Gelb, Ben-Ami Gradwohl, Joshua A. Frieman
The cold dark matter (CDM) model of structure formation, normalized on large scales, leads to excessive pairwise velocity dispersions on small scales. In an attempt to circumvent t…
Implications of New Gallex Results for the MSW Solution of the Solar Neutrino Problem
J. M. Gelb, Waikwok Kwong, S. P. Rosen
We compare the implications for 7Be and pp neutrinos of the two MSW fits to the new GALLEX solar neutrino measurements . Small mixing angle solutions tend to suppress the former as…
