The QED Radiator at order $α^3$
Abstract
The O(alpha^3) leading logarithmic contribution to the QED radiator is analytically computed. The effect of the correction on two-fermion physics at LEP1 and LEP2 is evaluated and critically compared with the one of already known next-to-leading O(alpha^2) corrections. The O(alpha^3) leading logarithmic corrections turn out to be relevant in view of the experimental precision already reached at LEP1 and foreseen at LEP2.Keywords
