Determination of TMD parton densities from HERA data and application to pp processes [DESY-THESIS-2018-024] Hamburg : Verlag Deutsches Elektronen-Synchrotron, DESY-THESIS 138 pp. (2018) [10.3204/PUBDB-2018-02949] = Dissertation, Universität Hamburg, 2018   The topic of this thesis is a new approach to solve the DGLAP evolution equation to obtain not only the collinear Parton Distribution Functions (PDFs) but also the Transverse Momentum Dependent (TMD) PDFs (TMDs). The DGLAP equation is solved with the Parton Branching (PB) method, which allows a determination of kinematic variables at every branching and a construction of the TMDs in a large range in longitudinal momentum fraction $x$ and evolution scale $\mu^2$.

The Particle Flow approach is a key aspect of the detectors for the International Linear Collider (ILC) which is a future linear lepton collider designed for precision physics studies at a center of mass energy up to 500 GeV.The CALICE Collaboration is developing highly granular calorimeters for future colliders.

Vlasov Simulation of Exotic Phase-Space Densities via Tree-Based Domain-Decomposition [DESY-THESIS-2018-022] Hamburg : Verlag Deutsches Elektronen-Synchrotron, DESY-THESIS 77 pp. (2018) [10.3204/PUBDB-2018-02704] = Masterarbeit, Universität Hamburg, 2018   Magnetic bunch compression is used to produce the high-brightnesselectron bunches needed for the operation of a free-electron laser.A longitudinal energy chirp -- imprinted on the bunch via off-crestacceleration -- results in the compression of the bunch in a subsequentdispersive section of the accelerator in form of a magnetic chicane.Such a setup sets the stage for the self-interaction of charge-densityinhomogeneities via the space-charge fields they generate within the bunch.This can potentially lead to an enhancement of initially present charge-densitymodulations; an effect known as microbunching amplification.Numerical simulation of this dynamics is encumbered by the fact thatphase-space densities of electron bunches encountered at free-electron laserstypically exhibit an exotic'' structure, as they form a thin, hair-like bandmeandering through phase-space.In this thesis, a Vlasov-simulation approach based on tree domain-decompositionis presented, that allows for the efficient simulation of these phase-spacedensities despite their exoticness.Further, a beam-dynamics model is presented, which most notably enables thetime-discrete treatment of collective space-charge effects in drift regions ofthe accelerator.Based on this model an arbitrary-order perturbation theory for themicrobunching gain in a bunch-compressor is conceived and applied to the caseof a long bunch with monochromatic density modulation.Finally, the results from theory and simulation are compared as part of thebenchmarking of the simulation code..
