Is $\alpha'$ also the $e\pm$ annihilation scale ?
A model for the annihilation of electron-positron pairs into hadrons for q/sup 2/=s>4 GeV/sup 2/ and up to the highest measured energies is developed. The main ingredients are point-like couplings between three resonances and photons and the high level of opening thresholds that follows from an e...
