R-Parity Violation Axiogenesis
Raymond T. Co, Keisuke Harigaya, Zachary Johnson +1
We show that the rotation of the QCD axion field, aided by violation from supersymmetric -parity violating couplings, can yield the observed baryon abundance. Strong sphal…
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,…
Axiogenesis from phase transition
Keisuke Harigaya, Isaac R. Wang
The baryon asymmetry of the universe may be explained by rotations of the QCD axion in field space and baryon number violating processes. We consider the minimal extension of the S…
Naturalness and the muon magnetic moment
Nima Arkani-Hamed, Keisuke Harigaya
We study a predictive model for explaining the apparent deviation of the muon anomalous magnetic moment from the Standard Model expectation. There are no new scalars and hence no n…
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…
Gravitational Waves and Dark Photon Dark Matter from Axion Rotations
Raymond T. Co, Keisuke Harigaya, Aaron Pierce
An axion rotating in field space can produce dark photons in the early universe via tachyonic instability. This explosive particle production creates a background of stochastic gra…
Electroweak-like Baryogenesis with New Chiral Matter
Kohei Fujikura, Keisuke Harigaya, Yuichiro Nakai +1
We propose a framework where a phase transition associated with a gauge symmetry breaking that occurs (not far) above the electroweak scale sets a stage for baryogenesis similar to…
