A study is presented of anomalous HVV interactions of the Higgs boson, including its CP properties. The study uses Higgs boson candidates produced mainly in vector boson fusion and gluon fusion that subsequently decay to a pair of τ leptons. The data were recorded by the CMS experiment at the LHC in 2016 at a center-of-mass energy of 13 TeV and correspond to an integrated luminosity of 35.9 fb$^{-1}$. A matrix element technique is employed...

A statistical combination of several searches for the electroweak production of charginos and neutralinos is presented. All searches use proton-proton collision data at s √ =13 s=13 TeV, recorded with the CMS detector at the LHC in 2016 and corresponding to an integrated luminosity of 35.9 fb−1. In addition to the combination of previous searches, a targeted analysis requiring three or more charged leptons (electrons or muons) is presented, focusing on the challenging scenario in...

Spacetime colour reconnection in Herwig 7

J. Bellm, C. B. Duncan, S. Gieseke, M. Myska & A. Siódmok
We present a model for generating spacetime coordinates in the Monte Carlo event generator Herwig 7, and perform colour reconnection by minimizing a boost-invariant distance measure of the system. We compare the model to a series of soft physics observables. We find reasonable agreement with the data, suggesting that pp-collider colour reconnection may be able to be applied in larger systems.

In 2017 a new pixel detector was installed in the CMS detector. This so-called Phase-1 pixel detector features four barrel layers in the central region and three disks per end in the forward regions. The upgraded pixel detector requires an upgraded data acquisition (DAQ) system to accept a new data format and larger event sizes. A new DAQ and control system has been developed based on a combination of custom and commercial microTCA parts. Custom...

Evidence for light-by-light (LbL) scattering, γγ → γγ, in ultraperipheral PbPb collisions at a nucleon-nucleon centerof- mass energy of 5.02 TeV is reported. LbL scattering processes are selected in events with just two photons produced, with transverse energy Eγ T > 2 GeV, pseudorapidity |ηγ| < 2.4; and diphoton invariant mass mγγ > 5 GeV, transverse momentum pγγ T < 1 GeV, and acoplanarity (1 − Δφγγ/π) < 0.01. After all selection criteria, 14 events...

Novel production method for large double-sided microstrip detectors of the CBM Silicon Tracking System at FAIR

P. Pfistner, M. Caselle, T. Blank, M. Weber & CBM Collaboration
The silicon sensors of the Silicon Tracking System of the Compressed Baryonic Matter experiment at FAIR, GSI are connected to the read-out electronics by low mass flexible microcables due to tight material budget restrictions. The cable length of up to 50 cm and its flexible nature make detector module assembly one of the most critical parts in STS. A novel low mass, low capacitance multilayer copper microcable has been designed and produced to facilitate detector...

Theorie und Numerik unidirektional verstärkter Faserverbundwerkstoffe: 3D Finite-Element-Untersuchungen der Faser-Matrix Mikroinstabilitäten

Jens Harich
The topic of this work is a study of the microbuckling behavior of unidirectional fiber-reinforced composite materials. Some alternative finite element discretizations are compared in order to model the characteristic cell. Transversely isotropic material behavior is taken into account to model some anisotropic fibers. The free surface of the matrix has also influence on the fiber microbuckling. The results are compared qualitatively and quantitatively with analytical solutions and experiments.

Azimuthal correlations between the two jets with the largest transverse momenta p T pT in inclusive 2-, 3-, and 4-jet events are presented for several regions of the leading jet p T pT up to 4TeV TeV . For 3- and 4-jet scenarios, measurements of the minimum azimuthal angles between any two of the three or four leading p T pT jets are also presented. The analysis is based on data from proton–proton collisions collected...

A new CMS Tracker is under development for operation at the High Luminosity LHC from 2026 onwards. It includes an outer tracker based on dedicated modules that will reconstruct short track segments, called stubs, using spatially coincident clusters in two closely spaced silicon sensor layers. These modules allow the rejection of low transverse momentum track hits and reduce the data volume before transmission to the first level trigger. The inclusion of tracking information in the...

An approach to investigate surface roughness influence on the running-in behaviour of mixed-lubricated sliding contacts using the finite element method = Ein Ansatz zur Untersuchung des Einflusses der Oberflächenrauheit auf das Einlaufverhalten von mischreibungsbehafteten Gleitkontakten unter Verwendung der Finite Elemente Methode

Stefan Reichert
Um den Einfluss der Oberflächenrauheit auf das Reibungs- und Verschleißverhalten zu untersuchen, stehen nur begrenzte experimentelle Möglichkeiten zur Verfügung. Bedingt durch die spanende Endbearbeitung von Lagerschalen und Wellen bewirkt eine Veränderung der Werkstücktopographie, resultierend aus der Variation der Schnittparameter im Herstellprozess, immer auch eine Veränderung der Welligkeit und der Grenzschicht einer Oberfläche. Daher ist es mit experimentellen Methoden aktuell nicht möglich, die Rauheit isoliert zu betrachten. Hierzu wird in der vorliegenden Forschungsarbeit eine Methode zur...
