Searches for GeV-Scale ALPs at RHIC
Kaori Fuyuto, Claudio Andrea Manzari, Hitoshi Murayama
We point out that ultra-peripheral Au+Au collision data collected at the Relativistic Heavy Ion Collider, operational during 2000-2026, can be used to search for axion-like particl…
GeV-scale QCD Axion
Hitoshi Murayama
In order to solve the strong CP problem, we study the possibility that the Peccei--Quinn symmetry is broken {\it below}\/ the QCD scale. We find that a QCD axion can be above GeV,…
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…
A High-Quality Axion from Exact SUSY Chiral Dynamics
T. Gherghetta, H. Murayama, B. Noether +1
We use supersymmetric chiral dynamics perturbed by anomaly-mediated supersymmetry breaking to obtain a high-quality, composite axion that solves the strong CP problem. The strong d…
A High-Quality Composite Pati-Salam Axion
Tony Gherghetta, Hitoshi Murayama, Pablo QuÃlez
We present a composite QCD axion model where the Peccei--Quinn (PQ) symmetry emerges as a high-quality, accidental symmetry. The axion potential is only modified by eight-fermion,…
