Development of a compact hard X-ray split-and-delay line for studying ultrafast dynamics at free electron laser sources [DESY-THESIS-2019-023] Hamburg : Verlag Deutsches Elektronen-Synchrotron, DESY-THESIS 140 pp. (2019) [10.3204/PUBDB-2019-03551] = Dissertation, Universität Hamburg, 2019   The study of condensed matter dynamics on ultrafast timescales is one of the key topics in modern material science research. Hard X-ray free-electron laser sources with extreme peak brightness and ultra short pulses provide excellent conditions for studying ultrafast dynamics in the time domain by employing such techniques as X-ray pump-probe spectroscopy or X-ray photon correlation spectroscopy.

An Update of the ABMP16 PDF Fit [arXiv:1909.03533; DESY-19-152; DO-TH 19/16; SAGEX-19-21] XXVII international workshop on deep-inelastic scattering and related subjects, DIS2019, TorinoTorino, Italy, 8 Apr 2019 - 12 Apr 2019   We present an updated version of the ABMP16 nucleon PDFs, which is tuned by using recent precise data on $W$- and $Z/\gamma^*$-production at the LHC and the final HERA data on DIS $c$- and $b$-quark production and by imposing a stringent $Q^2$-cut on the inclusive DIS data in order to avoid the impact of higher twist terms at small $x$ at HERA. The new $W$- and $Z$-boson production data, in particular the updated version of the ATLAS data at the c.m.s.

This allows for a series of unique measurements of observables sensitive to the multidimensional (spin) structure of the nucleon, in particular semi-inclusive deep-inelastic scattering (SIDIS) measurements, for which the HERMES dual-radiator ring-imaging Cherenkov counter provided final-hadron identification between 2 GeV to 15 GeV for pions, kaons, and (anti)protons.

The search is based on a data sample of proton-proton collisions at a center-of-mass energy of 13 TeV recorded by the CMS experiment at the CERN LHC and corresponding to a total integrated luminosity of 35.9 fb$^{-1}$.

Confronting EFT with artificial neural networks in the quest for physics beyondthe Standard Model - Probing new paths for measuring dimension-6 operators in top-quark physics at LHC Hamburg : University of Hamburg 64 pp. (2019) [10.3204/PUBDB-2019-03421] = Masterarbeit, University of Hamburg, 2019   As no sign of physics beyond the Standard Model has emerged at the Large Hadron Collider sofar, high precision measurements of particle properties and couplings become increasingly interesting.A commonly used language to interpret these measurements is effective field theory, inwhich higher-dimensional operators are added to the Standard Model. Traditional approachesmost commonly set constraints on anomalous couplings by employing and combining unfoldedmeasurements. [...] OpenAccess: PDF PDF (PDFA);
