Recently, advances in high-intensity laser technology have enabled the exploration of non-perturbative quantum electrodynamics (QED) in the strong-field regime. Notable aspects include nonlinear Compton scattering and Breit-Wheeler pair production, which can be observed when high-intensity laser pulses collide with relativistic electron beams. [...]

We show, both analytically andnumerically,thatnon-Gaussian tails in the probability density function of curvature perturbations arise in ultra-slow-roll inflation from the δN formalism, without invoking stochastic inflation. Previously reported discrepancies between both approaches are a consequence of not correctly accounting for momentum perturbations. [...]

The CMS at DESY outreach Instagram account provides science communication and outreach for a large experimental particle physics group. It aims to promote science, engage young scientists in outreach and showcase their work. [...]

A series of data samples was collected with the Belle~II detector at the SuperKEKB collider from March 2019 to June 2022. We determine the integrated luminosities of these data samples using three distinct methodologies involving Bhabha ($e^+e^- \to e^+e^-(n\gamma)$), digamma ($e^+e^- \to \gamma\gamma(n\gamma)$), and dimuon ($e^+e^- \to \mu^+ \mu^- (n\gamma)$) events.

The Photo Injector Test Facility at DESY in Zeuthen (PITZ) focuses on the development & optimization of high-brightness e-beam sources for FELs like the EuXFEL. The main scientific program is generation of intense e-beams characterized by small transverse emittance from the photo injector, a critical requirement for modern FELs. [...]

The Higgs boson was discovered by the ATLAS and CMS Collaborations in 2012 using data from Run 1 of the Large Hadron Collider (2010$-$2012). In Run 2 (2015$-$2018), about 140 fb$^{-1}$ of proton$-$proton collisions at a centre-of-mass energy of 13 TeV were collected by the ATLAS experiment. [...]

A survey is given on the current status of the theoretical description of unpolarized and polarized deep-inelastic scattering processes in Quantum Chromodynamics at large virtualities..

The field of bone regeneration has primarily focused on investigating fracture healing and nonunion in isolated musculoskeletal injuries. Compared to isolated fractures, which frequently heal well, fractures in patients with multiple bodily injuries (polytrauma) may exhibit impaired healing. [...]
