Description

We propose a new and rather unbiased way of determining the value of the strong coupling constant α, if transversally polarized electron-positron beams were available at LEP1. The ratio of azimuthal asymmetries for the production of hadrons to muons in e+e- annihilation is independent of any cut-off procedure and is very sensitive to the value of αs. Moreover we show that on top of Z resonance, it is free from any ambiguity stemming from Standard Model unknown parameters or the possible presence of New Physics
