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. [...]

Non-Gaussian tails without stochastic inflation
[DESY-24-071; IFT-UAM/CSIC-24-75; arXiv:2406.02417]
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. [...]

Measurement of the integrated luminosity of data samples collected during 2019-2022 by the Belle II experiment
[Belle II Preprint 2024-019; KEK Preprint 2024-16; arXiv:2407.00965]
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.

Emittance optimization studies at PITZ with laser pulse shaping
Free Electron Laser Conference, FEL2024, WarsawWarsaw, Poland, 19 Aug 2024 - 23 Aug 20242024-08-192024-08-23 1-3 ()  GO
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. [...]

Characterising the Higgs boson with ATLAS data from Run 2 of the LHC
[CERN-EP-2024-087; arXiv:2404.05498]
Physics reports 11, S037015732400382X () [10.1016/j.physrep.2024.11.001]  GO
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. [...]

Polytrauma impairs fracture healing accompanied by increased persistence of innate inflammatory stimuli and reduced adaptive response
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. [...]
