“…Besides the one-loop part of ∆r [11] it consists of the fermionic electroweak two-loop contributions [12], the purely bosonic two-loop contributions [13] and the QCD corrections of O(αα s ) [14,15]. Higher-order QCD corrections are known at O(αα 2 s ) [17,18].…”

We present the currently most accurate evaluation of the W boson mass, M W , in the Minimal Supersymmetric Standard Model (MSSM). The full complex phase dependence at the one-loop level, all available MSSM two-loop corrections as well as the full Standard Model result have been included. We analyse the impact of the different sectors of the MSSM at the one-loop level with a particular emphasis on the effect of the complex phases. We discuss the prediction for M W based on all known higher-order contributions in representative MSSM scenarios. Furthermore we obtain an estimate of the remaining theoretical uncertainty from unknown higher-order corrections. * email: Sven.Heinemeyer@cern.ch †

“…This paper discusses the complete computation of all electroweak two-loop corrections to sin 2 θ lept eff . In addition to the corrections to the prediction of the W -boson mass, which have been analyzed before [4,5], this includes all two-loop diagrams contributing to the Zl + l − vertex on the Z pole. The diagrams can be conveniently divided into two groups; fermionic contributions with at least one closed fermion loop, and bosonic contributions without closed fermion loops.…”

Recently exact results for the complete electroweak two-loop contributions to the effective weak mixing angle were published. This paper illustrates the techniques used for this computation, in particular the methods for evaluating the loop diagrams and the proper definition of Z-pole observables at next-to-next-to-leading order. Numerical results are presented in terms of simple parametrization formulae and compared in detail with a previous result of an expansion up to next-to-leading order in the top-quark mass. Finally, an estimate of the remaining theoretical uncertainties from unknown higher-order corrections is given. * email: Malgorzata.Awramik@desy.de †

Mixed EW-QCD leading fermionic three-loop corrections at $$ \mathcal{O} $$(αsα2) to electroweak precision observables

Measurements of electroweak precision observables at future electron-position colliders, such as the CEPC, FCC-ee, and ILC, will be sensitive to physics at multi-TeV scales. To achieve this sensitivity, precise predictions for the Standard Model expectations of these observables are needed, including corrections at the three- and four-loop level. In this article, results are presented for the calculation of a subset of three-loop mixed electroweak-QCD corrections, stemming from diagrams with a gluon exchange and two closed fermion loops. The numerical impact of these corrections is illustrated for a number of applications: the prediction of the W-boson mass from the Fermi constant, the effective weak mixing angle, and the partial and total widths of the Z boson. Two alternative renormalization schemes for the top-quark mass are considered, on-shell and $$ \overline{\mathrm{MS}} $$ MS ¯ .
