Axial Currents from CKM Matrix CP Violation

T. Konstandin

The first principle derivation of kinetic transport equations suggests that a CP-violating mass term during the electroweak phase transition can induce axial vector currents. Since…

Varying Couplings From Orbifold GUTs

Filipe Paccetti Correia, Michael G. Schmidt, Zurab Tavartkiladze

We discuss the variation of gauge couplings in time in the framework of orbifold constructions, due to a change of the extra compact dimension's size. Models with gauge coupling un…

Quantum Boltzmann equations for electroweak baryogenesis including gauge fields

Kimmo Kainulainen, Tomislav Prokopec, Michael G. Schmidt +1

We review and extend to include the gauge fields our derivation of the semiclassical limit of the collisionless quantum transport equations for the fermions in presence of a CP-vio…

Two-loop Feynman Diagrams in Yang-Mills Theory from Bosonic String Amplitudes

Boris Kors, Michael G. Schmidt

We present intermediate results of an ongoing investigation which attempts a generalization of the well known one-loop Bern Kosower rules of Yang-Mills theory to higher loop orders…

World Line Path Integrals as a Calculational Tool in Quantum Field Theory

Michael G. Schmidt, Christian Schubert

We report on the status of the string-inspired world line path integral formalism, a recently developed powerful tool for the reorganisation of standard perturbative amplitudes in…

The Electroweak Phase Transition - Standard and ``Beyond''

Michael G. Schmidt

We first review why a strongly first-order phase transition needed for baryogenesis is excluded in the electroweak standard model. We also comment on some intriguing effects in the…
