چکیده
We present the O(α) and O(α ln α) 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.

Order α 2 corrections to the decay rate of orthopositronium
Order α 2 corrections to the decay rate of orthopositronium are calculated in the framework of nonrelativistic QED. The resulting contribution is found to be in significant disagreement with one set of experimental measurements, though another experiment is in agreement with theory. The discrepancy between theory and experiment for the decay rate of orthopositronium has long been one of the out...

متن کاملBinding energy corrections in positronium decays
Positronium annihilation amplitudes that are computed by assuming a factorization approximation with on-shell intermediate leptons, do not exhibit good analytical behavior. We propose an ansatz which allows to include binding energy corrections and obtain the correct analytical and gauge invariance behavior of these QED amplitudes. As a consequence of these non-perturbative corrections, the par...
متن کاملO ( α 3 ln α ) corrections to muonium and positronium hyperfine splitting
The perturbative series for binding energies of a QED bound state are non-analytic in the fine structure constant and the expansion contains powers of α1 ln2 α, where n1 and n2 are some integer numbers. The appearance of logarithms of α is best explained by the fact that different scales, such as the mass m, the momentum mα and the typical energy mα control dynamics of the bound state. In a rec...

Positronium decays into two and three photons provide an interesting test of bound states Quantum Electrodynamics (QED). While the parapositronium (p-Ps) decay rate is well described by QED, it is known that the decay of orthopositronium (o-Ps) into three photons is still a controversial issue [1]. However, on the theoretical side there has been a major breakthrough recently and both decay rate...
