Electroweak Precision Tests with GigaZ
S. Heinemeyer, G. Weiglein
By running the prospective high-energy e^+e^- collider TESLA in the GigaZ mode on the Z resonance, experiments can be performed on the basis of more than 10^9 Z events. This will a…
Calculation of fermionic two-loop contributions to muon decay
A. Freitas, S. Heinemeyer, W. Hollik +2
The computation of the correction Δr 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…
Do electroweak precision data and Higgs-mass constraints rule out a scalar bottom quark with mass of O(5 GeV)?
M. Carena, S. Heinemeyer, C. E. M. Wagner +1
We investigate the phenomenological implications of a light scalar bottom quark, with a mass of about the bottom quark mass, within the minimal supersymmetric standard model. The s…
Higgs-mass predictions and electroweak precision observables in the Standard Model and the MSSM
S. Heinemeyer, G. Weiglein
Higher-order results for electroweak precision observables in the Standard Model are analyzed in view of the experimental accuracies achievable at the present and the next generati…
Physics Impact of GigaZ
J. Erler, S. Heinemeyer, W. Hollik +2
By running the prospective high-energy e^+ e^- collider TESLA in the GigaZ mode on the Z resonance, experiments can be performed on the basis of more than 10^9 Z events. They will…
Summary of the SUSY Working Group of the 1999 Les Houches Workshop
S. Abdullin, M. Drees, H. -U. Martyn +35
The results obtained by the Working Group on Supersymmetry at the 1999 Les Houches Workshop on Collider Physics are summarized. Separate chapters treat "general" supersymmetry, R-p…
