42. Dominant NNLO corrections to W-pair production near threshold.

The process of W-pair production close to threshold at an electron-positron collider is crucial for a precise determination of the W mass. In this talk we present the dominant NNLO electroweak corrections to the total cross section of e- e+ --> mu- \bar{nu} u \bar{d} X near the W-pair threshold computed in the framework of unstable-particle effective theory, and quantify their impact on the...

45. Three Loop Corrections to the MSSM Higgs Boson Mass

Dr Philipp Kant (Universität Karlsruhe)

We consider radiative corrections to the mass of the lightest Higgs Boson in the MSSM. In particular, the three-loop SUSY-QCD corrections are computed. We find that our corrections are of the order of 500MeV and thus relevant for both LHC and ILC. The scale dependency of the Higgs mass gets reduced by an order of magnitude compared to previous two-loop calculations, suggesting stability of the...

41. Oblique-parameter constraints on multi-Higgs-doublet models

Per Osland (Bergen university)

We present general expressions for the oblique parameters S, T, U, in the SU(2)xU(1) electroweak model with an arbitrary number of scalar SU(2) doublets, and an arbitrary number of scalar SU(2) singlets. Based on arXiv:0711.4022, arXiv:0802.4353
