The influence of quarks on the SU(3) deconfinement phase transition
, 1984 Karsch F. The influence of quarks on the SU(3) deconfinement phase transition. Nuclear Physics, A. 1984;418(23):467-476.We discuss the influence of quarks on the first order deconfinement phase transition present in pure SU(3) lattice gauge theory ...

Nuclear Physics A, 2003 A general introduction to the topological mechanism responsible for the absolute confinement of quarks inside hadronic bound states is given, including the effects of a finite instanton angle. We then propose a calculational technique for computing these states and their properties, where instead of topology we rely on a perturbative mechanism.

Improved hadronic measurements and spectral sums on the lattice
, 2008 In this thesis we address several topics of lattice QCD. As a first project we perform calculations of ground and excited states of light mesons. Especially the extraction of the excited states turns out be very difficult.

Phase transition from nuclear to quark matter
, 2005 We use the flavor SU(2) NJL model to describe both nuclear and quark matter, and construct phase diagrams to illustrate the phase transitions to normal quark matter (NQM) and color superconducting quark matter (SQM). We calculate the corresponding charge

Rare W → B c + γ decay up to the NNLO and NLL accuracy in QCD
Journal of High Energy PhysicsWe perform a detailed theoretical study of the rare radiative decay of the W boson into a B c meson and an on-shell photon. The decay amplitude is described by two independent form factors, which are calculated up to the next-to-next-to-leading order ...

New Aspects of Flavour Model Building in Supersymmetric Grand Unification [PDF]
, 2010 We derive predictions for Yukawa coupling ratios within Grand Unified Theories generated from operators with mass dimension four and five. These relations are a characteristic property of unified flavour models and can reduce the large number of free ...

Studying energy–energy correlators in pp collisions at the LHC with a jet-free event-topology method
European Physical Journal C: Particles and FieldsWe present a jet-free approach for measuring energy–energy correlators (EEC) in proton–proton (pp) collisions at the Large Hadron Collider (LHC), employing an event-topology method that does not rely on explicit jet reconstruction.
