Leptogenesis in Parity Solutions to the Strong CP Problem and Standard Model Parameters
Juanca Carrasco-Martinez, David I. Dunsky, Lawrence J. Hall +1
We study the simplest theories with exact spacetime parity that solve the strong CP problem and successfully generate the cosmological baryon asymmetry via decays of right-handed n…
A Heavy QCD Axion and the Mirror World
David I. Dunsky, Lawrence J. Hall, Keisuke Harigaya
We study the mirror world with dark matter arising from the thermal freeze-out of the lightest, stable mirror particle -- the mirror electron. The dark matter abundance is achieved…
Dark Radiation Constraints on Heavy QCD Axions
David I. Dunsky, Lawrence J. Hall, Keisuke Harigaya
The naturalness problem of PQ symmetry motivates study of the heavy QCD axion, with masses 1 MeV generated at scales above the QCD scale, and low values of the PQ symmetry…
Upper limit on the axion-photon coupling from magnetic white dwarf polarization
Christopher Dessert, David Dunsky, Benjamin R. Safdi
Polarization measurements of thermal radiation from magnetic white dwarf (MWD) stars have been proposed as a probe of axion-photon mixing. The radiation leaving the surface of the…
A Next-Generation Liquid Xenon Observatory for Dark Matter and Neutrino Physics
J. Aalbers, K. Abe, V. Aerne +591
The nature of dark matter and properties of neutrinos are among the most pressing issues in contemporary particle physics. The dual-phase xenon time-projection chamber is the leadi…
Gravitational Wave and CMB Probes of Axion Kination
Raymond T. Co, David Dunsky, Nicolas Fernandez +4
Rotations of an axion field in field space provide a natural origin for an era of kination domination, where the energy density is dominated by the kinetic term of the axion field,…
Sterile Neutrino Dark Matter and Leptogenesis in Left-Right Symmetric Theories
David Dunsky, Lawrence J. Hall, Keisuke Harigaya
Left-Right symmetric theories solve the strong CP problem and explain the small Higgs quartic coupling at high energy scales via the Higgs Parity mechanism, which forces the Higgs…
Dark Matter Detection, Standard Model Parameters, and Intermediate Scale Supersymmetry
David Dunsky, Lawrence J. Hall, Keisuke Harigaya
The vanishing of the Higgs quartic coupling at a high energy scale may be explained by Intermediate Scale Supersymmetry, where supersymmetry breaks at - GeV. The p…
Sterile Neutrino Dark Matter and Leptogenesis in Left-Right Higgs Parity
David Dunsky, Lawrence J. Hall, Keisuke Harigaya
The standard model Higgs quartic coupling vanishes at GeV. We study theories that incorporate the Higgs Parity mechani…
Sterile Neutrino Dark Matter in Left-Right Theories
Jeff A. Dror, David Dunsky, Lawrence J. Hall +1
gauge symmetry requires three right-handed neutrinos (), one of which, , can be sufficiently stable to be dark matter. In the early universe,…
Dark Matter, Dark Radiation and Gravitational Waves from Mirror Higgs Parity
David Dunsky, Lawrence J. Hall, Keisuke Harigaya
An exact parity replicates the Standard Model giving a Mirror Standard Model, SM SM. This "Higgs Parity" and the mirror electroweak symmetry are spontaneously…
Higgs Parity, Strong CP, and Dark Matter
David Dunsky, Lawrence J. Hall, Keisuke Harigaya
An exact spacetime parity replicates the electroweak interaction, the Higgs boson , and the matter of the Standard Model. This "Higgs Parity" and the mirror…
CHAMP Cosmic Rays
David Dunsky, Lawrence J. Hall, Keisuke Harigaya
We study interactions of cosmological relics, , of mass and electric charge in the galaxy, including thermalization with the interstellar medium, diffusion through inho…
