AbstractAbstract
[en] An overview of the status of four-loop tadpole calculations and their applications is given. Recent developments in reduction techniques for multi-loop integrals based on Integration-by-Parts, Laporta algorithm and Groeber bases are presented. Using a combined approach of these techniques we calculated the second moment of the heavy quark current correlator. The impact on determinations of charm and bottom quark masses is discussed.

AbstractAbstract
[en] Because of anomalies, chiral symmetry requires at least two species of quark. A class of strictly local fermionic actions with an exact chiral symmetry satisfying this bound on the number of flavors is discussed. (author)

AbstractAbstract
[en] An introduction to lattice QCD with emphasis on advanced fermion formulations and their simulation is given. In particular, overlap fermions will be presented, a quite novel fermionic discretization scheme that is able to exactly preserve chiral symmetry on the lattice. I will discuss efficiencies of state-of-the-art algorithms on highly scalable supercomputers and I will show that, due to many algorithmic improvements, overlap simulations will soon become feasible for realistic physical lattice sizes. Finally I am going to sketch the status of some current large scale lattice QCD simulations. (author)

AbstractAbstract
[en] The need for predictions of standard model processes at the LHC at leading order and beyond is motivated. Recent developments in computing scattering amplitudes are reviewed. I describe the limitations of tree-level predictions, and how they may be improved at next-to-leading order. The current status of the field is discussed. (author)

AbstractAbstract
[en] The seminar series 'Vienna central European seminar on particle physics and quantum field theory' has been created 2004 and is intended to provide interactions between leading researchers and junior physicists. This year 'Highlights in Computational Quantum Field Theory' has been chosen as subject. The present status of Monte Carlo event generation for collider experiments and the GRID technology are presented. In perturbative quantum field theory automation of loop and precision calculations are covered, at the nonperturbative level advances in lattice QCD as well as simulations of M-theory, supergravity and black holes.(author)

AbstractAbstract
[en] At a critical temperature QCD changes it behavior: quarks become deconfined and chiral symmetry is restored. As the two phenomena appear at roughly the same temperature, it has been speculated that they might be linked to each other. We revisit and study this idea by exploring the role of generalized fermionic boundary conditions. (author)

AbstractAbstract
[en] The methods for computing Feynman diagrams have become more and more sophisticated over the years. Lately much progress has been made to express them in terms of Harmonic Sums. In this talk I will show some techniques by which these sums can be manipulated. This is applied to two interesting problems: one is how to express Multiple Zeta Values into a minimal set and the other concerns the solving difference equations. These problems will be placed in their physics context. (author)

AbstractAbstract
[en] I present results of the NLO corrections for u+u to b+b+d+d in massless QCD. Along with this calculation a Feynman diagram based, general matrix element generator for one-loop amplitudes (GOLEM) is being developed, the status of which is also outlined in my talk. (author)

AbstractAbstract
[en] We construct a variational basis of interpolating fields containing both Jacobi-smeared quark sources of a Gaussian type as well as derivative quark sources. These interpolators are used to extract the ground and lowest lying excited states for pseudoscalar, scalar, vector and pseudovector mesons. (author)
