Description
The Monte Carlo event generator PHOKHARA has been widely used to simulate electron-positron annihilation into hadrons plus a hard photon with next-to-leading-order (NLO) accuracy. It includes virtual and soft-photon corrections to single-photon emission, as well as events with two hard real photons. In this talk, we present recent progress in extending PHOKHARA beyond NLO precision. First, we report new results for the pion-pair channel, incorporating the Generalised Vector Dominance Model as an improvement over the usual point-like treatment of pions. We then present the implementation of soft-photon resummation and discuss ongoing work on additional next-to-next-to-leading-order (NNLO) corrections.
