Orthopositronium lifetime: analytic results in O(alpha) and O(alpha^3 ln(alpha))

Abstract

We present the O(alpha) and O(alpha^3 ln(alpha)) corrections to the total decay width of orthopositronium in closed analytic form, in terms of basic transcendental numbers, which can be evaluated numerically to arbitrary precision.
