New Solutions to the Strong CP Problem
read the original abstract
We exhibit a solution to the strong CP problem in which ultraviolet physics renders the QCD theta angle physically unobservable. Our models involve new strong interactions beyond QCD and particles charged under both the new interactions and ordinary color.

Searching for long-lived ALPs with a laser-assisted optical dump
A laser-assisted optical dump could probe ALP-electron couplings down to ~10^-6 (10^-7) GeV^-1 with 16.5 (125) GeV electron beams, and when both couplings are present the Primakoff process improves the electron-coupli...

The structure of multi-axion solutions to the strong CP problem
Multi-axion theories solving the strong CP problem produce varied mass-coupling relations via a general sum rule that depends on the details of PQ symmetry breaking and anomaly alignments.

The structure of multi-axion solutions to the strong CP problem
Multi-axion solutions to the strong CP problem produce varied mass-coupling patterns set by PQ symmetry breaking structure and QCD-EM anomaly alignment, summarized by a general sum rule for N-axion systems.

Worldline effective field theory of inspiralling black hole binaries in presence of dark photon and axionic dark matter
Computes 1PN conservative dynamics for gravitational/EM/Proca fields and 2PN for scalar, plus radiation effects from axion-photon coupling at high PN orders in binary black hole systems with dark matter.
