Antimatter Gravity and the Results of the ALPHA‐g Experiment
Annalen der Physik, Volume 536, Issue 7, July 2024.The recent results of the ALPHA‐g experiment, which show gravitational attraction between antihydrogen atoms and the Earth, seem to undermine the success of repulsive‐gravity models in the cosmological field. Analyzing the theory of CPT gravity, two solutions are found that are consistent with the experimental results, while preserving the large‐scale ...

Cylindrically Symmetric Diffusion Model for Relativistic Heavy‐Ion Collisions
Annalen der Physik, Volume 536, Issue 5, May 2024.To account for particle production in relativistic heavy‐ion collisions at the Large Hadron Collider, a relativistic diffusion model with cylindrical symmetry is derived from nonequilibrium–statistical considerations. It propagates an initial state based on quantum chromodynamics in time toward a thermal equilibrium limit.

Non-relativistic quantum chromodynamics in parton showers
European Physical Journal C: Particles and FieldsMeasurements 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.

Limits on Dark Photons, Scalars, and Axion‐Electromagnetodynamics with the ORGAN Experiment
Annalen der Physik, Volume 536, Issue 1, January 2024.The nature of dark matter is one of the biggest mysteries in the Universe. ORGAN is an experiment which seeks to understand dark matter by figuring out what it is made of. In this article, the current sensitivity of ORGAN to various promising dark matter candidates is presented, and the future sensitivity is projected.

Running of the top quark mass at NNLO in QCD
Journal of High Energy PhysicsThe 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 ...

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.
