The exceptionally large dataset collected by the ATLAS and CMS detectors at the highest proton-proton collision energies provided by the LHC enables precision testing of theoretical predictions using an extensive sample of top quark events. One example of this is the spin correlation of top quarks, which can uniquely be probed due to the decay time being shorter than hadronisation time. [...]

In ultra-relativistic heavy-ion collisions, high rates of γ-γ processes occur through the interaction of the large electromagnetic fields of the heavy nuclei. For large impact parameters between the nuclei, i.e. [...]

CP violation in the kaon system can manifest itself in decays to final states containing neutral kaons. The effect is governed by an efficiency function that reflects the specific experimental setup. [...]

<jats:title>Abstract</jats:title><jats:p>The unification of conformal and fuzzy gravities with internal interactions is based on the facts that i) the tangent group of a curved manifold and the manifold itself do not necessarily have the same dimensions and ii) both gravitational theories considered here have been formulated in a gauge theoretic way. The gauge‐theoretic approach of gravities, commenting in particular on their diffeomorphism invariance, and the construction of conformal and noncommutative (fuzzy) gravity using the gauge‐theoretic framework are reviewed [...]

The DESY Photon Science Division Scientific Data Policy regulates the responsibilities and rights of the involved parties with respect to scientific data from public research collected at user facilities operated by DESY Photon Science (DESY-FS) and stored on DESY compute and IT infrastructure. It does not apply to other DESY departments, nor does it apply to scientific data generated through proprietary research through purchased (commercial) access..

Laser-driven dynamics in polyatomic molecules poses a complex many-body problem. Understanding intense light-matter interaction is crucial for steering intramolecular quantum dynamical processes. [...]

For the first time, an Ag-based catalyst is used in the gas phase non-oxidative dehydrogenation of methanol to dimethoxymethane. Auto-reductive behaviour of Ag species is observed, and the dynamic Ag oxidation state is identified as descriptive for the dynamic reaction course [...]

With no concrete evidence for nongravitational interactions of dark matter to date, it is natural to wonder whether dark matter couples predominantly to the Standard Model (SM)’s neutrinos. Neutrino interactions (and the possible existence of additional neutrinophilic mediators) are substantially less understood than those of other SM particles, yet this picture will change dramatically in the coming decades with new neutrino sources.
