Sudakov Enhancement of Electroweak Corrections
In perturbation theory the infrared structure of the electroweak interactions produces large corrections proportional to double logarithms log s m , similar to Sudakov logarithms in QED, when the scale s is much larger than the typical mass m of the particles running in the loops. These energy growing corrections can be particularly relevant for the planned Next Linear Colliders. We study these...

Matteo Beccaria and Edoardo Mirabella Dipartimento di Fisica, Università di Lecce, Via Arnesano, 73100 Lecce, Italy. b Istituto Nazionale di Fisica Nucleare, Sezione di Lecce Abstract Electroweak radiative corrections can be evaluated in the Sudakov approximation, a systematic high energy expansion known to be relevant for the analysis of future collider experiments in the TeV energy range. In ...

The Large Hadron Collider (LHC) will study processes at energies √ s much larger than the masses of the W and Z bosons. Radiative (Sudakov) corrections to such processes contain logarithms L = log(s/M W,Z), and one gets two factors of L for each order in perturbation theory [1]. At LHC energies, these Sudakov corrections are not small — a typical electroweak correction αL/(4π sin θW ) ∼ 0.15 at...
متن کاملSupersymmetric Sudakov corrections
For superpartner masses not much heavier than the weak scale M = MW, large logarithmic corrections of the Sudakov type arise at TeV energies. In this paper we discuss the general structure of electroweak supersymmetric (susy) Sudakov corrections in the framework of the infrared evolution equation method. We discuss Yukawa sector Ward-identities which lead to the exponentiation of the subleading...
