Advances in Searching for Galactic Axions with a Dielectric Haloscope (MADMAX)

Annalen der Physik, Volume 536, Issue 1, January 2024.
In this article the general concept of the MADMAX (Magnetized Disc and Mirror Axion experiment) is described. MADMAX is a dielectric haloscope aimed to detect dark matter axions. Recent updates of the magnet and the cryostat that will host different prototype radio frequency (RF) booster systems are presented.

Primer on Axion Physics

Annalen der Physik, Volume 536, Issue 1, January 2024.
A primer on axion physics, emphasizing an intuitive understanding of why the axion solves the strong CP problem. Abstract The canonical axion potential is reviewed, with an emphasis on the field theory underlying radial and angular modes of complex scalar fields.

Higgs‐induced screening mechanisms in scalar‐tensor theories

Annals of the New York Academy of Sciences, Volume 1531, Issue 1, Page 95-103, January 2024.
Abstract We consider the theory of a light conformally coupled scalar field, that is, one that is coupled directly to the Ricci scalar of the gravitational sector. This theory can be written equivalently as one of a light scalar that is coupled to the Standard Model of particle physics with a particular combination of Higgs‐portal couplings.

Non-relativistic quantum chromodynamics in parton showers

European Physical Journal C: Particles and Fields
Measurements of quarkonia isolation in jets at the Large Hadron Collider (LHC) have been shown to disagree with fixed-order non-relativistic quantum chromodynamics (NRQCD) calculations, even at higher orders.

Starting SQM 2024: Theory state-of-the-art [PDF]

EPJ Web of Conferences
I discuss the theoretical developments related to Strangeness in Quark Matter (SQM) leading up to the SQM2024 conference. These advances include mapping out the Quantum Chromodynamics phase diagram; puzzles that exist in hadron physics from light to ...

Flux tube in turbulent flow and quantum chromodynamics [PDF]

arXiv, 2009
Using some assumptions about the correlation function of velocity in a turbulent flow, a cylindrically symmetric tube-like solution is obtained. It is proposed that this turbulent flow is similar to a flux tube in quantum chromodynamics. Using similar assumptions for quantum chromodynamics, a flux tube filled with a color electric field is obtained ...

Dissociation of J/ψ and Y Using Dissociation Energy Criteria in N‐Dimensional Space

Advances in High Energy Physics, Volume 2024, Issue 1, 2024.
The analytical exact iteration method (AEIM) has been widely used to calculate N‐dimensional radial Schrodinger equation with medium‐modified form of Cornell potential and is generalized to the finite value of magnetic field (eB) with quasiparticle approach in hot quantum chromodynamics (QCD) medium.

Running of the top quark mass at NNLO in QCD

Journal of High Energy Physics
The running of the top quark mass (m t) is probed at the next-to-next-to-leading order in quantum chromodynamics for the first time. The result is obtained by comparing calculations in the modified minimal subtraction ( $$\overline{{\text{MS ...

The structure of the proton: The CT14 QCD global analysis

EPJ Web of Conferences, 2016
A brief description of the CT14 global analysis of quantum chromodynamics at next-to-next-to leading order (NNLO) from the CTEQ-TEAgroup is given. Predictions for standard candle processes at the LHC are illustrated together with the main features of the

Quantum Science and the Search for Axion Dark Matter

PRX Quantum, 2023
The dark-matter puzzle is one of the most important open problems in modern physics. The ultralight axion is a well-motivated dark-matter candidate, conceived to resolve the strong-CP problem of quantum chromodynamics.
