Level-Four Modular Symmetry Selected by the Harmonic Pattern of Quark and Lepton Masses
Vernon Barger
The mass ratios of the quarks and charged leptons follow a simple pattern. The logarithmic generation steps come in a two to one ratio, a note to its octave, and the ordering is mi…
Commensurate Structure of Quark and Lepton Mixing: Eighteenth Powers of One Parameter and a Digital-Clock Quantization of the Unitarity Triangles
Vernon Barger
We identify two commensurate structures in the measured quark and lepton mixing data, one multiplicative and one angular, and their exact relation. With the hierarchy parameter $\v…
The model: trimaximal first-column lepton mixing with charged-lepton -- breaking
Vernon Barger
The first column of the lepton mixing matrix carries two independent magnitude conditions: the trimaximal norm and the -- balance . P…
The KM3NeT 220 PeV event: a neutrino messenger from the grand unification scale?
Vernon Barger
The 220~PeV neutrino KM3-230213A, in tension with IceCube and Auger unless narrow, admits a two-body reading: relic decay with ~GeV. Con…
Generation as Compositeness: A Subconstituent Interpretation of the -Lattice Flavor Hierarchy
Vernon Barger
We interpret the -lattice flavor framework as a compositeness hierarchy: all three fermion generations are elementary chiral fields, but third-generation Yukawa couplings are un…
Natural SUSY with mixed axion/axino dark matter
Howard Baer, Vernon Barger, Kairui Zhang
While supersymmetric models provide a solution to the big hierarchy problem, natural SUSY is also allowed by the little hierarchy problem. In supersymmetric models which include th…
Unified Flavor: Lattice Quantization, Chain Locality, and a Dynamical Origin of Hierarchical Yukawas
Vernon Barger
We present Unified Flavor (UF), a framework that synthesizes the -lattice flavor hierarchy with a dynamical realization based on TeV-scale vectorlike fermion (VLF) chains. Hiera…
Lepton Mixing from a Lattice Flavon Model: A Two-Branch Octant-delta Prediction
Vernon Barger
We extend the single-flavon -lattice Froggatt--Nielsen (FN) framework, previously successful for quark masses and Cabibbo-Kobayashi-Maskawa (CKM) mixing, to the lepton sector. T…
Flavor in Ninths and a Discrete Gauge Origin of the QCD Axion
Vernon Barger
Quark and lepton hierarchies are organized by rational powers of a single parameter (the quark masses and mixings in ninths, the charged-lepton mass ratios in sixths). We argue tha…
CP-violating top-Higgs coupling in SMEFT
Vernon Barger, Kaoru Hagiwara, Ya-Juan Zheng
The total cross section of the process has strong dependence on the CP phase of the top Yukawa coupling, where the ratio of and …
End of the cosmic neutrino energy spectrum
L. A. Anchordoqui, V. Barger, H. Goldberg +5
There may be a high-energy cutoff of neutrino events in IceCube data. In particular, IceCube does not observe either continuum events above 2 PeV, or the Standard Model Glashow-res…
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…
Off--axis Beams and Detector Clusters: Resolving Neutrino Parameter Degeneracies
V. Barger, D. Marfatia, K. Whisnant
There are three parameter degeneracies inherent in the three--neutrino analysis of long--baseline neutrino experiments. We develop a systematic method for determining whether or no…
Supernova 1987A did not test the neutrino mass hierarchy
V. Barger, D. Marfatia, B. P. Wood
We dispel the misconception that data from SN 1987A favor the normal neutrino mass hierarchy over the inverted hierarchy for $\sin^2 θ_{13} \gsim 10^{-4}$. We find comparable fits…
How accurately can one test CPT conservation with reactor and solar neutrino experiments?
John N. Bahcall, V. Barger, Danny Marfatia
We show that the combined data from solar neutrino experiments and from the KamLAND reactor neutrino experiment can establish an upper limit on, or detect, potential CPT violation…
Inverting a Supernova: Neutrino Mixing, Temperatures and Binding Energy
V. Barger, D. Marfatia, B. P. Wood
We show that the temperatures of the emergent non-electron neutrinos and the binding energy released by a galactic Type II supernova are determinable, assuming the Large Mixing Ang…
E1 Working Group Summary: Neutrino Factories and Muon Colliders
D. Harris
We are in the middle of a time of exciting discovery, namely that neutrinos have mass and oscillate. In order to take the next steps to understand this potential window onto what w…
Neutrino Superbeam Scenarios at the Peak
V. Barger, D. Marfatia, K. Whisnant
We discuss options for U.S. long baseline neutrino experiments using upgraded conventional neutrino beams, assuming is chosen to be near the peak of the leading oscillation…
Testing radiative neutrino mass generation via R-parity violation at the Tevatron
V. Barger, T. Han, S. Hesselbach +1
An R-parity violating SUSY model with lepton-number violating couplings , i=2,3 can generate a neutrino mass spectrum that explains the recent results from neutrino oscil…
