ARES is an electron linear accelerator at the SINBAD facility at DESY. It aims to deliver reliable high-brightness beams with an energy in the range of 50 MeV to 150 MeV with fs to sub-fs bunch lengths. [...]

The next-to-leading order single-differential top quark-antiquark pair production cross section predictions are examined consistently using short-distance top quark mass schemes, with the evolution of the mass of the top quark performed in the MSR scheme $m_{\rm t}^{\rm MSR}(\mu)$ for scales $\mu$ below the $\overline{\rm MS}$ top quark mass $\overline{m}_{\rm t}(\overline{m}_{\rm t})$, and in the $\overline{\rm MS}$ scheme $\overline{m}_{\rm t}(\mu)$ for scales above. The implementation of a mass renormalization scale independent of the strong coupling renormalization scale and factorization scale in quantum chromodynamics allows investigating independent dynamical scale variations, and a scale choice of $R\sim 80$ GeV is demonstrated to be important for the stability of the cross-section predictions in the low top quark-antiquark pair invariant mass range.Moreover, a choice of semi-dynamical renormalization and factorization scales is preferred, and the findings are demonstrated in a theoretically consistent extraction of the top quark MSR mass from experimental data..

The Crab system, composed of a bright pulsar wind nebula (PWN) powered by the young energetic central pulsar \crabpulsar, has been observed across the electromagnetic spectrum for decades of investigation. Its emission in the gamma-ray band has challenged our understanding of the radiation and particle acceleration processes at play for such systems. [...]

PUNCH4NFDI, funded by the Germany Research Foundation initially for five years, is a diverse consortium of particle, astro-, astroparticle, hadron and nuclear physics embedded in the National Research Data Infrastructure initiative. In order to provide seamless and federated access to the huge variety of compute and storage systems provided by the participating communities covering their very diverse needs, the Compute4PUNCH and Storage4PUNCH concepts have been developed. [...]

In High Energy Physics, detailed and time-consuming simulations are used for particle interactions with detectors. To bypass these simulations with a generative model, the generation of large point clouds in a short time is required, while the complex dependencies between the particles must be correctly modelled. [...]

LUXE is a proposed near-future experiment along the European XFEL beamline aiming to make several new measurements in the non-perturbative regime of strong-field quantum electrodynamics (SFQED). The experiment will collide electrons and photons with a high-intensity laser in order to measure multiple non-linear processes unique to the extreme realm of SFQED, allowing the first chance to validate theoretical models in this unexplored regime. [...]

The Transverse Momentum Dependent (TMD) Parton Branching (PB) method is a Monte Carlo (MC) approach to obtain QCD high energy collider predictions grounded in ideas originating from the TMD factorization. It provides an evolution equation for the TMD parton distribution functions (TMDs) and a framework to use those within TMD MC generators.This work focuses on the structure of the PB Sudakov form factor. [...]

The paper presents the development and performance of the $^{57}$Fe Synchrotron Mössbauer Source (SMS) at the beamline P01 at PETRA III. A detailed description of the experimental setup is provided, including the optical elements and the critical role of high-quality iron borate crystals used as the Mössbauer source. [...]

In-situ measurements of ferroelectric polarization and diffraction under an applied electric field are critical for establishing accurate structure-property correlation. This method captures the dynamic response of ferroelectric materials. [...]

New, asymmetric quinizarin-Au(I)-NHC complexes were designed, isolated, and fully characterised including by single crystal X-ray crystallography. Cytotoxicity studies showed effective growth inhibition in HeLa cervical cancer cells with IC$_{50}$ values ranging from 2.4 μM to 5.3 μM [...]
