Low power integrated system for a simultaneous time and energy measurement in the PANDA micro-strip detector
Giessen : JLU Giessen, 179 p. (2017) = Dissertation, JLU Giessen, 2017
The PANDA experiment is one of the main projects foreseen at the Facility for Antiproton and Ion Research (FAIR). Its task is to measure the products of the reactions between an antiproton beam, with a beam momentum between 1.5 GeV/c and 15 GeV/c, and a proton or nucleon fixed target. [...]

Developments towards the technical design and prototype evaluation of the PANDA Endcap Disc DIRC
195 p. (2017) = Dissertation, JLU Giessen, 2017
The envisaged physics program of the PANDA (antiProton ANnihilation at Darmstadt) experiment at the future Facility for Antiproton and Ion Research (FAIR) requires excellent particle identification over the full solid angle. The Endcap Disc DIRC (EDD) will cover forward polar angles between 5 and 22° and is one of three dedicated subdetectors for the identification of charged hadrons and the separation of pions and kaons in particular. [...]

Beam energy dependence of dielectron production in Au+Au collisions from STAR at RHIC
Frankfurt am Main : Universitätsbibliothek Johann Christian Senckenberg, 210 pp. (2017) = Dissertation, JWGU Frankfurt, 2017
At sufficiently high temperatures and baryon densities, nuclear matter is expected to undergo a transition into the Quark-Gluon-Plasma (QGP) consisting of deconfined quarks and gluons and accompanied by chiral symmetry restoration. Signals of these two fundamental characteristics of Quantum-Chromo-Dynamics (QCD) can be studied in ultra-relativistic heavy-ion collisions producing a relatively large volume of high energy and nucleon densities as existent in the early universe. [...]

Thermal evolution of massive compact strange objects in a SU(3) chiral Quark Meson Model
Frankfurt am Main : Universitätsbibliothek Johann Christian Senckenberg, 278 p. (2017) = Dissertation, JWGU Frankfurt, 2017
In dieser Arbeit wurden thermodynamische Eigenschaften eines chiralen Quark Meson Modelles untersucht. Das chirale Quark Meson Model beschreibt die starke Wechselwirkung über den Austausch von Mesonen und zudem die thermische und dichteabhängige Entwicklung der Quarkmassen im Medium über die chirale Symmetrie.Im SU(2) Model wurde zunächst in mean field approximation gearbeitet, um im Anschluss den divergenten Vakuumterm mit einzubeziehen. [...]

Reconstruction of the low-mass dielectron signal in 1.23A GeV Au+Au collisions
Frankfurt am Main : Universitätsbibliothek Johann Christian Senckenberg, 212 p. (2017) = Dissertation, JWGU Frankfurt, 2017
QCD matter is expected to exist in different phases, when heated to high temperatures and getting highly compressed. Each phase could be characterized by distinct properties. [...]

Untersuchungen zu einer neuen Alvarez-Struktur für den GSI Post-Stripper
Frankfurt am Main : Universitätsbibliothek Johann Christian Senckenberg, 101 p. (2017) = Dissertation, JWGU Frankfurt, 2017
Im Rahmen dieser Arbeit wurden neue Ansätze zur Optimierung eines Alvarez Beschleunigers für Schwerionen untersucht. Dabei dient die Alvarez-Sektion des GSI UNILAC als Untersuchungsfeld, da für den Injektionsbetrieb für FAIR eine Erneuerung dieser Sektion erforderlich ist. [...]

Λ and K0s production in Au+Au collisions at 1.23A GeV
Frankfurt am Main : Universitätsbibliothek Johann Christian Senckenberg, 259 p. (2017) = Dissertation, JWGU Frankfurt, 2017
In April and May 2012 data on Au+Au collisions at beam energies of Ekin = 1.23A GeV were recorded with the High Acceptance Di-Electron Spectrometer, which is located at the GSI Helmholtz Center for Heavy Ion Research in Darmstadt, Germany. At this beam energy all hadrons containing strangeness are produced below their elementary production threshold. [...]

Interfaces between relativistic hydrodynamics and transport for the dynamical description of heavy ion collisions
Frankfurt am Main : Universitätsbibliothek Johann Christian Senckenberg, 179 p. (2017) = Dissertation, JWGU Frankfurt, 2017
In this doctoral thesis the transformation from relativistic hydrodynamics to transport and vice versa is studied. Approximations made by hybrid (hydrodynamics + transport) simulations of relativistic heavy ion collisions are discussed and their reliability is assessed at intermediate collision energies [...]
