Abstract

I reconsider the forward-backward asymmetry for flavoured quarks in electron-positron annihilation. I suggest an infrared-safe definition of this observable, such that the asymmetry may be computed in perturbative QCD with massless quarks. With this definition, the first and second order QCD corrections are computed.

Keywords

forward-backward asymmetry NNLO QCD corrections e+e- annihilation infrared safety
