Abstract

We compute

O (α^{3} \ln α)

corrections to the decay rates of para- and orthopositronium into two and three photons, respectively. For this calculation we employ the nonrelativistic QED regularized dimensionally and we explain how in this framework the logarithms of the fine-structure constant can be extracted.
