Holographic quark gluon plasma with flavor

open access: yes, 2008
In this thesis we explore the effects of chemical potentials or charge densities inside a thermal plasma, which is governed by a strongly coupled gauge theory.

Phenomenological aspects of an anisotropic quark-gluon plasma

open access: yes, 2010
In this work we investigate phenomenological aspects of an anisotropic quark-gluon plasma. In the first part of this thesis, we formulate phenomenologicalmodels that take into account the momentumspace anisotropy of the system developed during the ...

Inclusive B-decay spectra and IR renormalons.

open access: yes, 2010
I illustrate the role of infrared renormalons in computing inclusive B-decay spectra. I explain the relation between the leading ambiguity in the definition of Sudakov form factor exp(N /M) and that of the pole mass, and show how these ambiguities ...

Kollektive Phänomene im Nichtgleichgewichts-Quark-Gluon-Plasma

open access: yes, 2008
In this work we study the non-equilibrium dynamics of a quark-gluon plasma, as created in heavy-ion collisions. We investigate how big of a role plasma instabilities can play in the isotropization and equilibration of a quark-gluon plasma. In particular,

Quakes in solid quark stars

open access: yes, 2004
A starquake mechanism for pulsar glitches is developed in the solid quark star model. It is found that the general glitch natures (i.e., the glitch amplitudes and the time intervals) could be reproduced if solid quark matter, with high baryon density but

Centre vortices and the quark propagator [PDF]

open access: yes, 2008
PoS(ConfinementVIII)056It is thought that confinement and chiral symmetry breaking might be driven by the same mechanism. Centre vortices have long been considered a promising candidate for such a mechanism.

QUARKS IN THE UNIVERSE

open access: yesInternational Journal of Modern Physics E, 2007
Matter in its present form was formed when our Universe emerged from the quark-gluon phase (QGP) at about 30mus into its evolution. To explore this early period in the laboratory, we study highly excited matter formed in relativistic heavy ion collision experiments: heavy nuclei crash into each other, and form compressed and energetically excited ...

Extracting Quark Polarisations of the Nucleon using Hadron

open access: yes, 2008
The standard hadronisation models assume the fragmentation process to be spinindependent. Under this assumption it is possible to use unpolarised information about the scattering and fragmentation processes to extract polarised parton density functions ...

Schwinger-Dyson equations in QED and QCD the calculation of fermion-antifermion condensates [PDF]

open access: yes, 2007
We present non-perturbative solutions for the fermion and boson propagators of QED in both three- and four-dimensions, and QCD. In doing so, we solve the coupled system of Schwinger-Dyson equations numerically in Euclidean space, investigating ...
