Light-cone Hamiltonian flow for positronium. The numerical solutions

High Energy Physics - Theory 2007-05-23 v1

Abstract

The effective Hamiltonian, as obtained from applying the Hamiltonian flow equations to front form QED, are solved numerically for positronium. Both the exchange and the annihilation channels are included. The impact of different similarity functions is explicitly studied. Perfect numerical agreement with other methods is found.
