Description
The three independent amplitudes describing the decay of orthopositronium to three photons are evaluated in analytic form to one-loop order. The amplitudes are used to obtain the order-α and order-α2 open-quote open-quote square close-quote close-quote contributions to the orthopositronium decay rate as integrals over the two-dimensional phase space. The results for the decay rate contributions are Γ1=-10.286606(10)(α/π)ΓLO and Γ2(square)=28.860(2)(α/π)2ΓLO, where ΓLO is the lowest order rate. copyright 1996 The American Physical Society
