About the EW contribution to the relation between pole and MS-masses of the top-quark in the Standard Model

TL;DR

This paper reviews the electroweak contribution to the relation between pole and MS-masses of the top-quark in the Standard Model, emphasizing the significance of an optimal renormalization scale for minimal radiative corrections.

Contribution

It identifies an optimal IR-scale where electroweak corrections are minimized, aiding Higgs parameter extraction and effective Lagrangian construction.

Findings

Optimal IR-scale lies between Z-boson mass and twice W-boson mass.

Electroweak corrections can be minimized or nullified at this scale.

Results are relevant for Higgs self-coupling and effective theories.

Abstract

Results of our recent re-analysis of the electroweak contribution to the relation between pole and running masses of top-quark within the Standard Model is reviewed. We argue, that if vacuum of SM is stable, then there exists an optimal value of renormalization group scale (IR-point), at which the radiative corrections to the matching condition between parameters of Higgs sector and pole masses is minimal or equal to zero. Within the available accuracy, we find the IR-point to lie in an interval between value of Z-boson mass and twice the value of W-boson mass. The value of scale is relevant for extraction of Higgs self-coupling from cross-section as well as for construction of effective Lagrangian.
