# Two-Loop Electroweak Logarithms

@inproceedings{Jantzen2005TwoLoopEL, title={Two-Loop Electroweak Logarithms}, author={Bernd Jantzen and Johann h. Kuhn and Alexandr Penin and Vladimir A. Smirnov}, year={2005} }

We present the complete analytical result for the two-loop logarithmically enhanced contributions to the high energy asymptotic behavior of the vector form factor and the four-fermion cross section in a spontaneously broken SU(2) gauge model. On the basis of this result we derive the dominant two-loop electroweak corrections to the neutral current four-fermion processes at high energies.

One-loop electroweak Sudakov logarithms: a revisitation and automation

- Computer Science, PhysicsJournal of High Energy Physics
- 2022

This work revisits the algorithm of Denner and Pozzorini for the calculation of one-loop electroweak Sudakov logarithms and extends it to NLO EW corrections to squared matrix-elements that involve also QCD corrections on top of subleading LO terms and proposes a new approach in which the QED component is consistently removed.
