Sudakov Logarithms in Four-Fermion Electroweak Processes at High Energy
نویسنده
چکیده
We discuss recent results for the asymptotic behavior of fermion scattering amplitudes in the Sudakov limit. The results include next-to-next-to-leading logarithmic electroweak corrections and are used for the analysis of fermion-antifermion pair production in ee annihilation at high energy. The importance of the subleading logarithmic contributions is emphasized and the fermionic contributions to the Abelian form factor at two loops are discussed.

Subleading Sudakov Logarithms in Electroweak Processes *
Recent results for the asymptotic behavior of fermion scattering amplitudes in the Sudakov limit are presented including next-to-leading logarithmic corrections. These are used for the analysis of the dominant electroweak corrections to the fermion-antifermion pair production in e + e − annihilation at high energy.
متن کاملLogarithmic SUSY electroweak effects on four-fermion processes at TeV energies
We compute the MSSM one-loop contributions to the asymptotic energy behaviour of fermion-antifermion pair production at future lepton-antilepton colliders. Besides the conventional logarithms of Renormalization Group origin, extra SUSY linear logarithmic terms appear of ”Sudakov-type”. In the TeV range their overall effect on a variety of observables can be quite relevant and drastically differ...
متن کاملTwo-loop electroweak Sudakov logarithms for massive fermion scattering
We study the asymptotic behaviour of two-loop electroweak corrections at energies Q2 ≫ M2 W, where logarithms of the type ln(Q2/M2 W) become dominant. The calculation of the leading and next-to-leading logarithmic terms for massless and massive fermion-scattering processes is summarized. The derivations are performed diagrammatically within the spontaneously broken electroweak theory. We find t...
متن کاملSumming up Subleading Sudakov Logarithms
We apply the strategy of regions within dimensional regularization to find functions involved in evolution equations which govern the asymptotic dynamics of the Abelian form factor and four-fermion amplitude in the SU(N) gauge theory in the Sudakov limit up to the next-to-leading logarithmic approximation. The results are used for the analysis of the dominant electroweak corrections to the ferm...

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...
