Single-spin asymmetries observed in polarised deep-inelastic scattering are important probes of hadron structure. The Sivers asymmetry provides information about the transverse momentum of the struck quark and can be related to final-state interactions. [...]

Misfit layered compounds (MLCs) are incommensurate super-lattices made up of two repeating subunits and are promising for different applications due to the possibility of a synergetic combination of the properties of the employed sublayers. A means of fine-tuning a specific MLC is to alloy one of the elements in the system [...]

Fragmentation functions (FFs) are essential nonperturbative QCD inputs for predicting hadron production cross sections in high energy scatterings. In this study, we present a joint determination of FFs for light charged hadrons through a global analysis at next-to-leading order (NLO) in QCD. [...]

Over the past two decades, laser plasma accelerators (LPAs) have emerged as a groundbreakingtechnology with immense potential for electron acceleration. Their ability to sustainexceptionally high accelerating gradients, on the order of 100 GV/m, and provide electronbunches with only few femtoseconds duration, promises a compact, cost-effective solutionfor numerous industrial, commercial, and medical applications. [...]

A formula for the loss rate of electrons from a stored beam due to the so-called "Touschek Effect" is derived starting with the exact M~ller scattering crosssection. For rectangular distribution of transverse momentum, this formula is integrated explicitly. [...]

The PETRA IV storage ring is a project planned to upgrade the synchrotron light source PETRA III at DESY. The main aim is to decrease the horizontal emittance as low as 20 pmrad. [...]

A comprehensive insight into ultrafast dynamics of photo-switchable materials is desired for efficient control of material properties through light excitation. Here, we study a polycrystalline spin crossover thin film as a prototypical example and reveal the sequential photo-switching dynamics, from local molecular rearrangement to global lattice deformation. [...]

In this study, we investigate the precipitation kinetics of Cu in 15–5 PH maraging stainless steel during high-temperature thermal treatments in the fully austenitic state. This provides direct evidence that Cu precipitation can occur in the austenite phase of martensitic or ferritic steels [...]

We establish a simple yet general parameterization of Higgs-muon interactions within the effective field theory frameworks, including both the Higgs Effective Field Theory (HEFT) and the Standard Model Effective Field Theory (SMEFT). We investigate the potential of a muon collider, operating at center-of-mass energies of 3 and 10 TeV, to probe Higgs-muon interactions. [...]

Constrained Friction Processing (CFP), a novel friction-based technique, has been developed to efficiently process fine-grained magnesium (Mg) rods, expanding the potential applications of biodegradable Mg alloys in medical implants. This study investigates the enhancement of mechanical properties through the implementation of multiple pass CFP (MP-CFP) in comparison to the conventional single pass CFP. [...]
