An algorithm for calculating the radiation field of a charged point particle performing a helical motion in an infinite cylindrical waveguide with a multilayer side wall is found. The number of layers and their filling is arbitrary. [...]

During its first phase, from 2004 up to the end of 2012, the H.E.S.S. (High Energy StereoscopicSystem) experiment observed the extragalactic skies for more than 2700 hours. [...]

The equivalence principle and the inverse-square law of gravity could be violated at short distances (10$^{-6}$–10$^{-12}$ m) by scalars sporting a coupling gN to nucleons and mass eV ≲ m$_ϕ$ ≲ MeV. We show for the first time that stringent bounds on the existence of these scalars can be derived from the observed cooling of nearby isolated neutron stars (NSs). [...]

Among other restrictions, vacuum stability is a theoretical constraint for vacuumconfigurations in BSM theories to be allowed or excluded. But due to multidimensionalfield spaces, computing the vacuum stability is a challenging task. [...]

We present a search for an invisible hidden-sector particle $ X_{\rm{inv}}$, produced in $B^0 \to \bar{D}^0 X_{\rm{inv}}$ and $B^\pm\to h X_{\rm{inv}}$ decays, where $h = π^\pm$, $K^\pm$, $D_{s}^\pm$, $p^\pm$. The search is performed using $e^+ e^-$ collision data recorded with the Belle detector, corresponding to 711~fb$^{-1}$. [...]

In this talk we present Helmholtz ID at Home (HIDaH) - an OpenID Connect Provider for testing and development. Testing the integration of applications into identity federations may require relying on staging systems where arbitrary identities can't be simulated easily or require running resource-intensive identity providers on local development machines. [...]

The dimensionality of a layered material, i.e. the number of 2D layers bound together, is a structural property underpinning the functional properties of the material. [...]
