Calculating Axion-Matter Couplings in String Theory
Joshua N. Benabou, Naomi Gendler, Thomas R. Harvey +1
In this work we calculate, for the first time, the dominant perturbative contributions to axion--matter couplings explicitly in string theory. Concretely, we compute these coupling…
GUEST: Gravitational Universe Exploration with Satellite Tracking. A passive satellite laser-ranging mission for the dark gravitational Universe
Diego Blas, Aurélien Hees, F. Javier Atapuerca +78
GUEST is a space mission concept whose central objective is the detection of gravitational waves (GWs) in the microhertz band -- a physics-rich frequency window that no other prese…
Heterotic String Theory Suggests a QCD Axion Near 0.5 neV
Joshua N. Benabou, Giulio Alvise Dainelli, Mario Reig +1
We show that in heterotic string theory -- and dual corners of the landscape including Type I string theory -- the QCD axion mass is bounded from below by neV, a…
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…
Wide-Angle Effects in the Power Spectrum Multipoles in Next-Generation Redshift Surveys
Joshua N. Benabou, Isabel Sands, Henry S. Grasshorn Gebhardt +2
As galaxy redshift surveys expand to larger areas on the sky, effects coming from the curved nature of the sky become important, introducing wide-angle (WA) corrections to the powe…
The Galaxy Bispectrum in the Spherical Fourier-Bessel Basis
Joshua N. Benabou, Adriano Testa, Chen Heinrich +2
The bispectrum, the three-point correlation in Fourier space, is a crucial statistic for studying many effects targeted by the next-generation galaxy surveys, such as primordial no…
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…
Electromagnetic modeling and science reach of DMRadio-m
DMRadio Collaboration, A. AlShirawi, V. Ankel +45
DMRadio-m is an experiment that is designed to be sensitive to KSVZ and DFSZ QCD axion models in the 10--200\,MHz (41 neV -- 0.83 eV/) range. The experiment uses…
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…
