Scintillation screens made of various inorganic materials are widely used for transverse beam profile diagnostics at all kinds of accelerators. The monitor principle is based on the particles¿ energy loss and its conversion to visible light. [...]

We compute the coupling $\alpha_\mathrm{qq}$ defined in terms of the static quark force by simulating the $\mathrm{SU}(3)$ Yang-Mills theory at lattice spacings down to $10^{-2}$~fm, keeping the volume large. In order to systematically improve the approach to the continuum, we subtract the leading cutoff effects in Symanzik's effective theory, resumming theleading $\log(a/r)$-term by renormalization group improvement. [...]

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. [...]

In recent years, Open Scientific Infrastructures have become an important tool for providing researchers and society with scientific information. Research institutes and universities worldwide actively plan and implement archivesof their scientific output [...]

The positions of the nearly twenty-thousand silicon sensors of the CMS central tracking system must be determined with a precision better than their intrinsic resolution in order to provide an optimal reconstruction of charged particle trajectories. The procedure, referred to as the alignment, includes also the adjustment of the orientations and the determination of the deviation from flatness of the sensor surfaces.Data-driven methods used to carefully align the detector and validate the alignment are presented using CMS Run 2 data, collected from 2016 to 2018. [...]

The recently deployed DeepTau algorithm for the discrimination of taus from light flavor quark or gluon induced jets, electrons, or muons is an ideal example for the exploitation of modern deep learning neural network techniques. With the current algorithm a suppression of misidentification rates by factors of two and more have been achieved for the same identification efficiency for taus compared to the MVA identification algorithms used for the LHC Run-1, leading to significant performance gains for many tau related analyses. [...]

A precise luminosity measurement is critical to determine fundamental parameters of the standardmodel and to constrain or to discover beyond-the-standard-model phenomena at LHC. The lumi-nosity determination at the LHC interaction point 5 with the CMS detector, using proton-protoncollisions at 13 TeV during Run 2 of the LHC (2015–2018), is reported. [...]

We present a lattice calculation of the leading hadronic contribution to the anomalous magnetic moment of the muon. This work is based on a subset of the CLS ensembles with $N_f = 2+1$ dynamical quarks and a quenched charm quark. [...]

The “long slab” is a new prototype for the SiW-Ecal, a silicon tungsten electromagnetic calorimeter for the International Large Detector (ILD) at the future International Linear Collider (ILC). The new prototype has been evaluated with cosmics, radioactive sources and with 3 GeV electrons in beam tests at the DESY facility, Hamburg. [...]

The performance of the ATLAS Forward Proton Time-of-Flight (ToF) Cherenkov detector is studied using the ATLAS data collected in 2017 during the LHC Run2. The detailed analysis of the results, including detector efficiency and time resolution of the ToF detector, is discussed. [...]
