Clearing up the Strong problem
Joshua N. Benabou, Anson Hook, Claudio Andrea Manzari +2
The absence of a neutron electric dipole moment (EDM) constrains the quantum chromodynamics (QCD) theta angle to be less than one part in ten billion, posing the Strong proble…
String Theory and Grand Unification Suggest a Sub-Microelectronvolt QCD Axion
Joshua N. Benabou, Katherine Fraser, Mario Reig +1
Axions, grand unification, and string theory are each compelling extensions of the Standard Model. We show that combining these frameworks imposes strong constraints on the QCD axi…
Search for Axions in Magnetic White Dwarf Polarization at Lick and Keck Observatories
Joshua N. Benabou, Christopher Dessert, Kishore C. Patra +4
We present the most sensitive search to date for light axion-like particles with masses below a micro-eV, using spectropolarimetric data collected from the Lick and Keck Observator…
Time-delayed gamma-ray signatures of heavy axions from core-collapse supernovae
Joshua N. Benabou, Claudio Andrea Manzari, Yujin Park +3
Heavy axions that couple to both quantum electrodynamics and quantum chromodynamics with masses on the order of MeV - GeV and high-scale decay constants in excess of G…
Axion mass prediction from adaptive mesh refinement cosmological lattice simulations
Joshua N. Benabou, Malte Buschmann, Joshua W. Foster +1
The quantum chromodynamics (QCD) axion arises as the pseudo-Goldstone mode of a spontaneously broken abelian Peccei-Quinn (PQ) symmetry. If the scale of PQ symmetry breaking occurs…
The Cosmological Dynamics of String Theory Axion Strings
Joshua N. Benabou, Quentin Bonnefoy, Malte Buschmann +2
The quantum chromodynamics (QCD) axion may solve the strong CP problem and explain the dark matter (DM) abundance of our Universe. The axion was originally proposed to arise as the…
Signatures of Primordial Energy Injection from Axion Strings
Joshua N. Benabou, Malte Buschmann, Soubhik Kumar +2
Axion strings are horizon-size topological defects that may be produced in the early Universe. Ultra-light axion-like particles may form strings that persist to temperatures below…
Detecting axion dark matter beyond the magnetoquasistatic approximation
Joshua N. Benabou, Joshua W. Foster, Yonatan Kahn +2
A number of proposals have been put forward for detecting axion dark matter (DM) with grand unification scale decay constants that rely on the conversion of coherent DM axions to o…
