Fermion Traces Without Evanescence

Nikolai Zerf

We outline the evaluation of -dimensional fermion traces () built by products of Dirac- matrices suitable for a uniform dimensional continuation. Such a conti…

RG analysis at higher orders in perturbative QFTs in CMP

Nikolai Zerf

In this contribution we report on the perturbative determination of -functions and anomalous dimensions for the chiral Ising, chiral XY and chiral Heisenberg Gross-Neveu-Yukawa…

Three-loop quark form factor at high energy: the leading mass corrections

Tao Liu, Alexander A. Penin, Nikolai Zerf

We compute the leading mass corrections to the high-energy behavior of the massive quark vector form factor to three loops in QCD in the double-logarithmic approximation.

O(alpha_s alpha_t) (non)decoupling effects within the top-sector of the MSSM

L. Mihaila, N. Zerf

In this paper we compute the threshold corrections to the running strong coupling constant, the top-Yukawa coupling and the top-quark mass within the MSSM. T…

Irreducible tensor basis and general Fierz relations for Bhabha scattering like amplitudes

Tao Liu, Nikolai Zerf

We construct an irreducible s- and t-channel tensor basis for Bhabha scattering like amplitudes based on the properties of the underlying Lorentz symmetry in four space-time dimens…

Two-loop Bhabha Scattering at High Energy beyond Leading Power Approximation

Alexander A. Penin, Nikolai Zerf

We evaluate the two-loop contribution to the wide-angle high-energy electron-positron scattering in the double-logarithmic approximation. The origin and the gen…
