A Tachyonic Gluon Mass: Between Infrared and Ultraviolet
S. J. Huber, M. Reuter, M. G. Schmidt
The gluon spin coupling to a Gaussian correlated background gauge field induces an effective tachyonic gluon mass. It is momentum dependent and vanishes in the UV only like 1/p^2.…
Nonperturbative Contributions to the Hot Electroweak Potential and the Crossover
S. J. Huber, A. Laser, M. Reuter +1
We discuss nonperturbative contributions to the 3-dimensional one-loop effective potential of the electroweak theory at high temperatures in the framework of the stochastic vacuum…
Application of the Worldline Path Integral Method to the Calculation of Inverse Mass Expansions
D. Fliegner, P. Haberl, M. 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 case of a massive sc…
The 2-loop MSSM finite temperature effective potential with stop condensation
D. Bodeker, P. John, M. Laine +1
We calculate the finite temperature 2-loop effective potential in the MSSM with stop condensation, using a 3-dimensional effective theory. We find that in a part of the parameter s…
