The requirement of electroweak naturalness in simple supersymmetric models motivates the existence of a cluster of four light higgsinos with mass $100 - 300$ GeV, the lighter the better. While such light compressed spectra may be challenging to observe at the LHC, future $e^+e^-$ colliders with $\sqrt{s} > 2$m(higgsino) would serve as both a SUSY discovery machine and a precision microscope.We study signatures of higgsino pair production at the ILC based on full, Geant4-based simulation of the ILD detector concept.

Dielectric laser driven particle acceleration (DLA) is one of the candidates for novel high-gradient technologies to reduce the footprint of large scale particle acceleration facilities. On the other hand these devices can be used to interact with the particle beams of state-of-the-art photon science machines, especially with FELs, to manipulate the longitudinal phase space in a compact and cost effective way.

In the recent years, the production, application and research of commercially pure titanium, titanium alloys and titanium aluminides have advanced considerably. In this keynote paper, information is provided on important achievements in the German titanium industry, governmental and non-governmental research organisations and universities. [...]

Due to their outstanding mechanical properties, excellent corrosion resistance and biocompatibility titanium and titanium alloys are the first choice for medical engineering products. Alloys currently used for implant applications are Ti-6Al-4V (ELI) and Ti-6Al-7Nb. [...]

Elektronik und Firm-/Software wird mit spezialisierten Anforderungen in vielen For-schungsprojekten benötigt. So haben viele Forschungszentren und auch Univer-sitäten Entwicklungsgruppen, die sich diesen Aufgaben stellen. [...]

Non-perturbative renormalization of O(a) improved tensor currents

MAXI J1820+070 is a new low-mass microquasar hosting a black hole recently discovered in X-rays by the MAXI instrument. It is the counterpart of ASASSN-18ey, discovered in optical a few days before by ASAS-SN. [...]

The FCC at CERN, a proposed 100-km circular facility with several colliders in succession, culminates with a 100 TeV proton-proton collider. It offers a vast new domain of exploration in particle physics, with orders of magnitude advances in terms of Precision, Sensitivity and Energy. [...]
