Recalculation of W and Z radiative corrections and a top quark mass estimate
Abstract
Description
The newly published top mass prediction of 85.1 GeV conflicts with indirect limits on the top mass, based on precision measurements interpreted by calculations using dimensional regularization. The top quark contribution to part of the electroweak W and Z vacuum polarization tensor is recomputed using the symmetrical theory of generalised functions. The squared top mass coefficient is larger by a factor 1.44. The indirect limits on the top mass based on this computation should therefore be divided by 1.2. Further recomputation and data analysis is needed.
