Description
The process of W-pair production close to threshold at an electron-positron collider is crucial for a precise determination of the W mass. In this talk we present the dominant NNLO electroweak corrections to the total cross section of e- e+ --> mu- \bar{nu} u \bar{d} X near the W-pair threshold computed in the framework of unstable-particle effective theory, and quantify their impact on the W-mass determination. We also discuss the implementation of realistic experimental cuts on invariant masses and angles in the EFT formalism.
