Static and dynamic properties of the pion from continuum modelling of strong QCD [PDF]

open access: yes, 2010
We present nonperturbative numerical solutions for the quark propagator Schwinger-Dyson equation (SDE) and pseudoscalar meson Bethe-Salpeter equation (BSE) at and beyond the rainbow-ladder truncation level of this system of equations.

Quark and Gluon Form Factors at Three Loops in Perturbative QCD [PDF]

open access: yes, 2009
We compute the quark and gluon form factors at up to three-loop order within massless perturbative Quantum Chromodynamics by studying the photon-quark-anti-quark vertex and the effective vertex of a Higgs boson and two gluons.

One-loop operator matching in the static heavy and domain-wall light quark system with O(a) improvement

open access: yes, 2011
We discuss perturbative O(g2a) matching with static heavy quarks and domainwall light quarks for lattice operators relevant to B-meson decays and B0–¯B 0 mixing. The chiral symmetry of the light domain-wall quarks does not prohibit operator mixing at O(a)

The phase transition to the quark-gluon plasma and its effect on hydrodynamic flow [PDF]

open access: yes, 2005
It is shown that in ideal relativistic hydrodynamics a phase transition from hadron to quark and gluon degrees of freedom in the nuclear matter equation of state leads to a minimum in the excitation function of the transverse collective ...

Impact of dark matter on strange quark stars described by different quark models

open access: yesEuropean Physical Journal C: Particles and Fields
Dark matter is hypothesized to interact with ordinary matter solely through gravity and may be present in compact objects such as strange quark stars. We treat strange quark stars admixed with dark matter as two-fluid systems to investigate the potential

Phenomenological aspects of an anisotropic quark-gluon plasma [PDF]

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 ...

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 ...
