pQCD energy loss and thermal field theory in small systems
… by considering a single, massless, scalar field that has been geometrically confined by means of Dirichlet boundary conditions. This toy model reveals, via thermal field theoretic techniques, that quantum fields are very sensitive to the presence of a boundary, presenting significant …

Strangeness production in a quark-gluon plasma
… Chapter 2 discusses the Cutkosky rules and their thermal field theory counterparts, the Kobes-Semenoff rules. The influence of the medium is brought into consideration through Braaten-Pisarski resummation. In Chapter 3 we use the Cutkosky rules to calculate the standard QCD quark production …

Thermal particle production in the early universe
… early universe which is in the state of a hot thermal plasma. Already at leading order in the gauge coupling constant multiple rescattering off soft (p ~ gT) gauge bosons has to be included which leads to nontrivial interference terms that must be taken into account. This phenomenon is known …

Finite system size effects on the effective coupling in scalar quantum field theory
… Indeed it has been shown that free scalar thermal field theory receives ∼ 40% corrections to the usual thermodynamic quantities when confined using Dirichlet boundary conditions with characteristic lengths set by central p + p collisions. Furthermore, the potential importance of asymmetric …
