QCD axion bubbles in the presence of ALP resonant conversion

Communications in Theoretical Physics
Abstract The QCD axion bubbles can form due to an explicit breaking of the Peccei–Quinn symmetry in the early Universe. In this paper, we investigate the modified formation of a QCD axion bubble in the presence of an axionlike particle (ALP), considering its resonant conversion to a QCD axion. We consider a general scenario where the QCD

Bounds on PBH fraction in a stimulated axion/ALP decay scenario

In this work, we show that stimulated decay of axions or axion-like particles (ALP) in black hole superradiance is an efficient way to find and hunt primordial black holes (PBH). When de Broglie's wavelength of the axion/ ALP is comparable or larger than the black hole horizon radius, a large population of them accumulates in the surroundings of the ...

The QCD axion sum rule

Journal of High Energy Physics
We demonstrate that the true QCD axion that solves the strong CP problem can be found in all generality outside the customary standard QCD band, with QCD being the sole source of Peccei-Quinn breaking.

Searching for axion forces with spin precession in atoms and molecules

Journal of High Energy Physics
We propose to use atoms and molecules as quantum sensors of axion-mediated monopole-dipole forces. We show that electron spin precession experiments using atomic and molecular beams are well-suited for axion searches thanks to the presence of co ...

A Non-Inflationary Axion and ALP Misalignment Mechanism

Based on considerations of quantum gravity, global symmetries which lead to axions as pseudo Nambu-Goldstone bosons after low scale symmetry breaking cannot be exact at the Planck scale. Here, we show that Planck-suppressed terms which yield this symmetry breaking may provide a non-inflationary misalignment mechanism which can generate coherent ...
