Event Structure in the Production of High Mass Photon Pairs
The event structure associated with the production of massive photon pairs is studied to ${\cal O}(α^2/alpha_s)$. The cross sections for two photon and two photon plus one jet events are given. The Dalitz plot structure of events with two photons and a jet is also presented. These distributions will provide checks on our understanding of the production mechanisms for massive photon pairs, a signal thought to be important for searches for the Higgs boson in the intermediate mass region.
