### New scenario of QCD axion clump formation I: Linear analysis

- Physics
- 2021

The QCD axion acquires the potential through the non-perturbative effect of the QCD matters around the QCD phase transition. During this period, the direct interaction between the axion and the QCD…

### Thermal Axion Production at Low Temperatures: A Smooth Treatment of the QCD Phase Transition.

- PhysicsPhysical review letters
- 2022

We study thermal axion production around the confinement scale. At higher temperatures, we extend current calculations to account for the masses of heavy quarks, whereas we quantify production via…

### Topology and axions in QCD

- Physics
- 2020

QCD axions are at the crossroads of QCD topology and Dark Matter searches. We present here the current status of topological studies on the lattice, and their implication on axion physics. We outline…

### Axions in Baryon Chiral Perturbation Theory

- PhysicsProceedings of RDP online PhD school and workshop "Aspects of Symmetry" — PoS(Regio2021)
- 2022

I give an overview of recent developments in the study of the coupling of the QCD axion to nucleons and other octet baryons. I demonstrate how axions can be included into heavy baryon chiral…

### Flavor violating axions in the early Universe

- PhysicsPhysical Review D
- 2022

Flavor violating axion couplings can be in action before recombination, and they can ﬁll the early universe with an additional radiation component. Working within a model-independent framework, we…

### Thermal QCD Axions across Thresholds

- PhysicsJournal of High Energy Physics
- 2021

Abstract
Thermal axion production in the early universe goes through several mass thresholds, and the resulting rate may change dramatically across them. Focusing on the KSVZ and DFSZ frameworks for…

### Selective enhancement of the QCD axion couplings

- PhysicsPhysical Review D
- 2021

We present a mechanism wherein the QCD axion coupling to nucleons, photons, or electrons can be enhanced selectively without increasing the axion mass. We focus in particular on the axion-nucleon…

### Running in the ALPs

- Physics
- 2020

The couplings of axion-like particles are probed by different experiments across a huge range of energy scales. Accordingly, a consistent analysis of the corresponding constraints requires the use of…

- PhysicsJournal of Cosmology and Astroparticle Physics
- 2022

The QCD axion acquires the potential through the non-perturbative effect of the QCD matters around the QCD phase transition. During this period, the direct interaction between the axion and the QCD…

### Axions: Theory and Cosmological Role

- Physics
- 2013

We review recent developments in axion cosmology. Topics include axion cold dark matter, axions from topological defects, axion isocurvature perturbation and its non-Gaussianity, and axino/saxion…

### Axions and the Dark Matter of the Universe

- Physics, Education
- 1983

Spin(10) axion models are constructed which offer the intriguing possibility that axions comprise all or a significant part of the dark matter of the Universe.

### Round Table on Axions and Axion-like Particles

- PhysicsProceedings of XIII Quark Confinement and the Hadron Spectrum — PoS(Confinement2018)
- 2019

In this contribution, based on the discussion at a round table of the XIII Quark Confinement and the Hadron Spectrum - Confinement conference, we review the main properties of the QCD axion and, more…

### Model of visible QCD axion

- Physics
- 2015

We pursue a class of visible axion models where the axion mass is enhanced by strong dynamics in a mirrored copy of the Standard Model in the line of the idea put forward by Rubakov. In particular,…

### A collider observable QCD axion

- Physics
- 2016

A bstractWe present a model where the QCD axion is at the TeV scale and visible at a collider via its decays. Conformal dynamics and strong CP considerations account for the axion coupling strongly…
