Ever since its discovery at the LHC in 2012, the Higgs boson is regarded as a messenger from yet charted realms of particle physics, beyond the so-called Standard Model. It is thus expected to play a unique role in understanding many open questions about our universe - from the electroweak phase transition and its relation to baryogenesis to the nature of dark matter and the origin of the mass and flavour hierarchy among quarks and leptons.

A fast orbit feedback system is under development for the upcoming PETRA IV ring of DESY. It is integral to achieving a diffraction-limited photon beam quality in this fourth-generation light source. [...]

The hadron collider phase of the Future Circular Collider (FCC-hh) is a proton-proton collider operating at a center-of-mass energy of 100 TeV. It is one of the most ambitious projects planned for the rest of this century and offers ample opportunities in the hunt for new physics, both through its direct detection reach as well as through indirect evidence from precision measurements.Extracting a precision measurement of the Higgs self-coupling from the Higgs pair production cross-section will play a key role in our understanding of electroweak symmetry breaking, as the self-coupling gives insight into the nature of the Higgs potential.

In this demo, we build upon VRS-NeRF to provide an implementation for real-time variable rate shading (VRS) in virtual reality (VR). Here, we demo a recent advancement of Neural Radiance Fields (NeRF) merging multiple pixels into one reducing the overall rendering time. [...]

In this work we report experimental compression of 9.4 mJ, 9.4 W, and 1.2 picosecond long pulses down to 7 mJ, 13 fs at 1 kHz in two cascaded stages with gas filled multi-pass cells (MPCs). The output from the first, argon filled MPC is compressed to <50 fs. [...]

The aim of LUXE (Laser Und XFEL Experiment based at DESY, Hamburg) is to measure strong-field QED effects with high precision. In order to create electric fields stronger than the so-called Schwinger limit, it is planned to collide a high-intensity laser pulse with either high-energy electrons up to $16.5\,\mathrm{GeV}$ or high-energy photons.These two configurations either result in non-linear Compton scattering or Breit-Wheeler interactions which can be studied by measuring rates and kinematics of secondary particles created at the interaction point like high-energy electrons, positrons and photons.For the detection of electrons, with expected fluxes of the order of $10^4$ to $10^9$ particles in an area of $15\,\mathrm{cm}\times1\,\mathrm{mm}$ per event, a Cherenkov detector in combination with magnetic deflection for high-precision spectrometry will be used.This contribution will present the simulation-based design of the Cherenkov detector, as well as first operation experience obtained with a prototype.
