Supernova neutrinos can tell us the neutrino mass hierarchy independently of flux models
V. Barger, Patrick Huber, Danny Marfatia
We demonstrate that the detection of shock modulations of the neutrino spectra from a galactic core-collapse supernova is sufficient to obtain a high significance determination of…
Axion Models with High-Scale Supersymmetry Breaking
V. Barger, Cheng-Wei Chiang, Jing Jiang +1
Inspired by the possibility of high-scale supersymmetry breaking in the string landscape where the cosmological constant problem and the gauge hierarchy problem can be solved while…
Neutral currents and tests of three-neutrino unitarity in long-baseline experiments
V. Barger, S. Geer, K. Whisnant
We examine a strategy for using neutral current measurements in long-baseline neutrino oscillation experiments to put limits on the existence of more than three light, active neutr…
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…
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…
