Which Bosonic Loop Corrections are Tested in Electroweak Precision Measurements?
S. Dittmaier, D. Schildknecht, G. Weiglein
The nature of the electroweak bosonic loop corrections to which current precision experiments are sensitive is explored. The set of effective parameters $\De x$, $\De y$, and $\eps…
On the Observation of Bosonic Loop Corrections in Electroweak Precision Experiments
S. Dittmaier, D. Schildknecht, G. Weiglein
We investigate the structure of the experimentally significant electroweak bosonic loop corrections to the leptonic weak mixing angle, the leptonic Z-boson decay width, and the W-b…
Radiative Corrections to in the Electroweak Standard Model
A. Denner, S. Dittmaier, M. Strobel
The cross-section for with arbitrary polarized photons is calculated within the electroweak Standard Model including the complete virtual and soft-photonic …
Stable Calculations for Unstable Particles: Restoring Gauge Invariance
Ernestos N. Argyres, Wim Beenakker, Ansgar Denner +6
We discuss theoretical and phenomenological aspects of the use of boson propagators with energy-dependent widths in predictions for high-energy scattering processes. In general, ga…
Gauge invariance, gauge-parameter independence and properties of Green functions
Ansgar Denner, Stefan Dittmaier, Georg Weiglein
The application of the background-field method to the electroweak Standard Model is reviewed and further explored. Special emphasis is put on questions of gauge invariance and gaug…
Integrating out the Standard Higgs Field in the Path Integral
Stefan Dittmaier, Carsten Grosse-Knetter
We integrate out the Higgs boson in the electroweak standard model at one loop and construct a low-energy effective Lagrangian assuming that the Higgs mass is much larger than the…
