Development of a standard test and calibration procedure for the hardware of the Radio Neutrino Detector RNO-G 135 pp. (2020) = Masterarbeit, University of Erlangen, 2020 Restricted: PDF PDF (PDFA); 2021-03-1810:40 [PUBDB-2021-01464] Master Thesis Necker, J. D. ; Franckowiak, A. ; Kowalski, M. A Search for High-Energy Neutrinos from Core-Collapse Supernovae 92 pp. (2020) = Masterarbeit, Humboldt Universität zu Berlin, 2020 Since the discovery of high energetic cosmic rays their origin poses an open question. High- energy neutrino emission is considered a smoking-gun signature of cosmic ray production.

Optimizing the triggering strategy for the detection of cosmic rays with the Radio Neutrino Observatory Greenland (RNO-G) 1-90 (2020) = Masterarbeit, Humboldt Universität zu Berlin, 2020 A promising technique to measure neutrinos above 10 PeV is the detection of radio signals generated by the Askaryan effect. The effect is caused by neutrino-induced particle cascades in dense media e.g. [...] Restricted: PDF PDF (PDFA); 2021-03-1010:24 [PUBDB-2021-01385] Master Thesis Ly, C. ; Ferber, T. ; Kasieczka, G. Shower shape conversion between electrons and photons in Belle II using Cycle Generative Adversarial Network DESY-Hamburg : DESY 87 pp. (2021) = Masterarbeit, University of Hamburg, 2021 Simulation is essential to high-energy physics. The application of simulation ranges from development of software to the analysis of physical processes.

Optimizing the Machine Learning techniques in the $\it H$ $\rightarrow$ $\tau \tau$ analysis with CMS data [DESY-THESIS-2021-001] Hamburg : Verlag Deutsches Elektronen-Synchrotron, DESY-THESIS 82 pp. (2021) [10.3204/PUBDB-2021-01074] = Masterarbeit, Universität Hamburg, 2021   This work is dedicated to optimize and improve the machine learning techniques usedin the $\it H$ $\rightarrow$ $\tau \tau$ analysis in the channel where the tau leptons decay to a e $\mu$ pair. The measurement is performed using data, corresponding to an integrated luminosity of 59.7 fb$^{-1}$, collected by the CMS experiment at a center-of-mass energy of 13 TeV during 2018.

Production of coherent 150 nm light via 7$^{\text{th}}$ harmonic generation for nuclear spectroscopy applications Hamburg 87 pp. (2021) = Masterarbeit, University of Hamburg, 2021 The $7^{\text{th}}$ harmonic generation of $1030\,\text{nm}$ light constitutes a rather unexplored regime within the field of harmonic generation. The resulting coherent light with a wavelength of roughly $150\,\text{nm}$ can be utilized for a wide range of novel applications, in particular the recently emerging field of nuclear spectroscopy of the Thorium-229 isotope nucleus.

Nonlinear Herriott-type Multipass Cells Pulse Post-Compression at High Compression Factor - (2020) = Masterarbeit, Ruhr University Bochum, 2020 2020-12-1714:37 [PUBDB-2020-05063] Master Thesis Dresselhaus, J. L. ; Osterhoff, J. ; Schmidt, B. ; et al Paving the way of high repetition rate laser wakefield acceleration by solving heat induced grating deformation issues 62 pp. (2020) [10.3204/PUBDB-2020-05063] = Masterarbeit, University of Hamburg, 2020   The goal of this thesis was to enable high repetition rate Laser Wakefield Acceleration(LWFA) by solving heat induced grating deformation issues in a Chirped PulseAmplification (CPA) based 25 TW Ti:sapphire laser system centred at 800 nm. Thesepreviously limited the intensity and wavefront quality of the pulse. [...] Published on 2020-06-11.

Search for $\it tZq$ in dilepton final states with Machine Learning techniques 55 pp. (2020) [10.3204/PUBDB-2020-04784] = Masterarbeit, Universit`a degli Studi di Milano - Bicocca, 2020   In this work, events in which a single top quark is produced in association with a Z-boson are investigated. Particular focus is on final states in which two leptons originate from the Z boson and the top quark decays hadronically.
