Electroweak two-loop corrections to the MW-MZ mass correlation in the Standard Model
A. Freitas, W. Hollik, W. Walter +1
Recently exact results for the complete fermionic two-loop contributions to the prediction for the W-boson mass from muon decay in the electroweak Standard Model have been publishe…
KIT Superconducting Undulator Development -- Story of a successful industrial collaboration & future prospects
B. Krasch, A. Bernhard, E. Bründermann +9
Undulators are X-ray sources widely used in synchrotron storage rings and free-electron laser facilities. With the commercial availability of low-temperature superconductors, a new…
Two-loop electroweak contributions to
A. Freitas, S. Heinemeyer, W. Hollik +2
A review is given on the quantum correction in the -- mass correlation at the electroweak two-loop level, as derived from the calculation of the muon lifetime in the St…
Complete fermionic two-loop results for the M_W-M_Z interdependence
A. Freitas, W. Hollik, W. Walter +1
The complete fermionic two-loop contributions to the prediction for the W-boson mass from muon decay in the electroweak Standard Model are evaluated exactly, i.e. no expansion in t…
Calculation of fermionic two-loop contributions to muon decay
A. Freitas, S. Heinemeyer, W. Hollik +2
The computation of the correction Îr in the W-Z mass correlation, derived from muon decay, is described at the two-loop level in the Standard Model. Technical aspects which become…
