Perturbative Contributions to the Electroweak Interface Tension
J. Kripfganz, A. Laser, M. G. Schmidt
The main perturbative contribution to the free energy of an electroweak interface is due to the effective potential and the tree level kinetic term. The derivative corrections are…
Axial Couplings on the World-Line
Myriam Mondragon, Lukas Nellen, Michael G. Schmidt +1
We construct a world-line representation for the fermionic one-loop effective action with axial and also vector, scalar, and pseudo-scalar couplings. We use this expression to comp…
Inverse Mass Expansions from Worldline Path Integrals - Higher Order Coefficients and Ordering Problems
Denny Fliegner, Peter Haberl, Michael G. Schmidt +1
Higher order coefficients of the inverse mass expansion of one--loop effective actions are obtained from a one--dimensional path integral representation. For the evaluation of the…
Yukawa Couplings for the Spinning Particle and the World Line Formalism
Myriam Mondragon, Lukas Nellen, Michael G. Schmidt +1
We construct the world-line action for a Dirac particle coupled to a classical scalar or pseudo-scalar background field. This action can be used to compute loop diagrams and the ef…
The High-Temperature Two-Loop Effective Potential of the Electroweak Theory in a General 't Hooft Background Gauge
J. Kripfganz, A. Laser, M. G. Schmidt
We calculate the high-temperature two-loop effective potential using a general 't~Hooft background gauge. The dependence on the gauge-fixing parameter is investigated. The effe…
