Description

We analyse subleading electroweak effects in the top-antitop resonance production region in e+ e- collisions which arise due to the decay of top quarks into Wb. These are NLO corrections adopting the non-relativistic power counting v ∝αs ∝√(α). In contrast to the QCD corrections which have been calculated (almost) up to N3LO, the NLO electroweak contributions have not been fully known so far, but are mandatory for the required accuracy at a future linear collider. We also present results with cuts on the invariant masses of the W+ b and W- anti b pairs that enhance the top-quark signal.
