A guidance of the approval workflow at DESY for the FS division..

Das bundesweit agierende Netzwerk Teilchenwelt ist ein Netzwerk zur Förderung von Teilchenphysik in der Gesellschaft. Hierbei werden vor allem Jugendliche und Lehrkräfte angesprochen, die anhand zweier authentischer Projekte lernen können, wie (Astro-)Teilchenphysiker Erkenntnisse gewinnen [...]

A guidance of the approval workflow at DESY for the PITZ Collaboration..

This document provides a comprehensive summary of the state-of-the-art, challenges, and prospects in the experimental and theoretical study of the strong coupling $\alpha_s$. The current status of the seven methods presently used to determine $\alpha_s$ based on: (i) lattice QCD, (ii) hadronic $\tau$ decays, (iii) deep-inelastic scattering and parton distribution functions fits, (iv) electroweak boson decays, hadronic final-states in (v) e+e-, (vi) e-p, and (vii) p-p collisions, and (viii) quarkonia decays and masses, are reviewed. [...]

Combined measurements of the total and differential cross-sections of Higgs boson production are performed with proton-proton collisions recorded by the ATLAS detector at the Large Hadron Collider. The data correspond to an integrated luminosity of 139 fb$^{−1}$ produced at a center-of-mass energy of 13 TeV. [...]

This note contains spectrum of b → (s, d)γ candidates selected in early Phase III data overlaidwith expectations for continuum events and background B ̄B events. The plot also shows thedifference between observed number of events and the background expectations..

This note presents photon detection eciency data-to-simulation ratio distributions in the barrelregion of the electromagnetic calorimeter of the Belle II detector at the SuperKEKB asymmetricenergy electron-positron collider. They are computed using 71:2 fb

A precise simulation of electromagnetic shower properties in the ATLAS calorimeter is crucial for the identification of particle showers originating from electrons and photons. AtlFast3, the next-generation of fast simulation in ATLAS, precisely simulates the properties of electromagnetic showers, but is limited by the accuracy of the full Geant4 simulation, upon which its parametrization is based. [...]

The current baseline construction schedule of the Pixel detector of the ATLAS Phase-2 Inner Tracker (ITk) is in tension with its foreseen installation date during Long Shutdown (LS) 3. Different staged-installation scenarios are being discussed that could help advancing the construction schedule. [...]
