Angular decomposition of tensor products of a vector

Gregory S. Adkins

The tensor product of $L$ copies of a single vector, such as $p_{i_{1}} ... p_{i_{L}}$ , can be analyzed in terms of angular momentum. When $p_{i_{1}} ... p_{i_{L}}$ is decomposed into a su…

Positronium energy levels at order $m α^{7}$ : Product contributions in the two-photon-annihilation channel

Gregory S. Adkins, Lam M. Tran, Ruihan Wang

Ongoing improvements in the measurement of positronium transition intervals motivate the calculation of the $O (m α^{7})$ corrections to these intervals. In this work we focus on corr…
