CMB Signals of Neutrino Mass Generation
Z. Chacko, Lawrence J. Hall, Takemichi Okui +1
We propose signals in the cosmic microwave background to probe the type and spectrum of neutrino masses. In theories that have spontaneous breaking of approximate lepton flavor sym…
Neutrino mass limits from SDSS, 2dFGRS and WMAP
V. Barger, Danny Marfatia, Adam Tregre
We investigate whether cosmological data suggest the need for massive neutrinos. We employ galaxy power spectrum measurements from the Sloan Digital Sky Survey (SDSS) and the Two D…
Progress in the physics of massive neutrinos
V. Barger, D. Marfatia, K. Whisnant
The current status of the physics of massive neutrinos is reviewed with a forward-looking emphasis. The article begins with the general phenomenology of neutrino oscillations in va…
LSND anomaly from CPT violation in four-neutrino models
V. Barger, D. Marfatia, K. Whisnant
The LSND signal for \barν_μto \barν_e oscillations has prompted supposition that there may be a fourth light neutrino or that CPT is violated. Neither explanation provides a good f…
The structure of electroweak corrections due to extended gauge symmetries
R. S. Chivukula, H. -J. He, J. Howard +1
This paper studies models with extended electroweak gauge sectors of the form SU(2) x SU(2) x U(1) x [SU(2) or U(1)]. We establish the general behavior of corrections to precision…
B_K from quenched QCD with exact chiral symmetry
Nicolas Garron, Leonardo Giusti, Christian Hoelbling +2
We present a calculation of the standard model ΔS=2 matrix element relevant to indirect CP violation in K->ππdecays which uses Neuberger's chiral formulation of lattice fermions. T…
Hiding relativistic degrees of freedom in the early universe
V. Barger, James P. Kneller, Paul Langacker +2
We quantify the extent to which extra relativistic energy density can be concealed by a neutrino asymmetry without conflicting with the baryon asymmetry measured by the Wilkinson M…
Suppression of baryon number violation in electroweak collisions: Numerical results
F. Bezrukov, D. Levkov, C. Rebbi +2
We present a semiclassical study of the suppression of topology changing, baryon number violating transitions induced by particle collisions in the electroweak theory. We find that…
Effective number of neutrinos and baryon asymmetry from BBN and WMAP
V. Barger, James P. Kneller, Hye-Sung Lee +2
We place constraints on the number of relativistic degrees of freedom and on the baryon asymmetry at the epoch of Big Bang Nucleosynthesis (BBN) and at recombination, using cosmic…
Flavor Constraints on Theory Space
E. H. Simmons, R. S. Chivukula, N. Evans
Composite Higgs models based on the chiral symmetries of ``theory space'' can produce Higgs bosons with masses of order 100 GeV from underlying strong dynamics at scales up to 10 T…
Unitarity of the Higher Dimensional Standard Model
R. Sekhar Chivukula, Duane A. Dicus, Hong-Jian He +1
We study the unitarity of the standard model (SM) in higher dimensions. We show that the essential features of SM unitarity remain after compactification, and place bounds on the h…
Semiclassical Study of Baryon and Lepton Number Violation in High-Energy Electroweak Collisions
F. Bezrukov, D. Levkov, C. Rebbi +2
We make use of a semiclassical method for calculating the suppression exponent for topology changing transitions in high-energy electroweak collisions. In the Standard Model these…
Little Inflatons and Gauge Inflation
David E. Kaplan, Neal Weiner
Cosmological inflation gives a natural answer for a variety of cosmological questions, including the horizon problem, the flatness problem, and others. However, inflation yields ne…
The Little Higgs from a Simple Group
David E. Kaplan, Martin Schmaltz
We present a model of electroweak symmetry breaking in which the Higgs boson is a pseudo-Nambu-Goldstone boson. By embedding the standard model SU(2) x U(1) into an SU(4) x U(1) ga…
WMAP and Inflation
V. Barger, Hye-Sung Lee, Danny Marfatia
We assay how inflationary models whose properties are dominated by the dynamics of a single scalar field are constrained by cosmic microwave background (CMB) data from the Wilkinso…
