“…In addition, the universal subleading corrections for external fermions, transversely as well as longitudinally polarized gauge bosons from Refs. [5,9] are in perfect agreement with one loop calculations in the SM fields [10,11]. Thus the physical picture that emerges is clear.…”

“…For processes with Yukawa enhanced SL contributions, the overall Sudakov suppression is enhanced. For processes with a large angle dependence, however, we must also include terms like log u t log s M 2 for which only one loop results are known [10,12]. Also higher order renormalization group corrections of O α n β 0 log 2n−1 s M 2 should be inlcuded via a running coupling in each loop correction in analogy to QCD [13,14].…”

At energies much larger than the mass of the weak gauge bosons, electroweak radiative corrections can lead to significant corrections. At 1 TeV the one loop corrections can be of ${\cal O} (20 %)$ due to large contributions of the Sudakov type. We summarize recent progress in the evaluation and resummation of the double and single logarithmic corrections to general scattering amplitudes for fermions, transversely as well as longitudinally polarized external lines.Comment: contribution to LCWS2000 at Fermila

At energies ($\sqrt{s}$) much higher than the electroweak gauge boson masses ($M$) large logarithmic corrections of the scale ratio $\sqrt{s}/M$ occur. While the electroweak Sudakov type double (DL) and universal single (SL) logarithms have recently been resummed, at higher orders the electroweak renormalization group (RG) corrections are folded with the DL Sudakov contributions and must be included for a consistent subleading treatment to all orders. In this paper we derive first all relevant formulae for massless as well as massive gauge theories including all such terms up to order ${\cal O} (\alpha^n \beta_0 \log^{2n-1} \frac{s}{M^2})$ by integrating over the corresponding running couplings. The results for broken gauge theories in the high energy regime are then given in the framework of the infrared evolution equation (IREE) method. The analogous QED-corrections below the weak scale $M$ are included by appropriately matching the low energy solution to the renormalization group improved high energy results. The corrections are valid for arbitrary external lines and largest in the scalar Goldstone and Higgs boson sector as well as for transverse gauge bosons. At TeV energies, these SL-RG terms change scattering cross sections in the percentile regime at two loops and are thus non-negligible for precision objectives at future linear colliders.Comment: 23 pages, 4 figures, uses LaTeX2
