Radiative pion-pair production in disperon QED
Yizhou Fang, Sophie Kollatzsch, Adrian Signer, Max Zoller
Abstract
Based on the previously developed disperon QED method for incorporating data input into loop processes in Monte Carlo codes, we calculate eeππγ at NLO and include the pion vector form factor within the form-factor scalar QED approximation wherever it is physically justified. By also considering contributions beyond, for which the form-factor scalar QED approach is less well justified, we gain insight into the associated theory uncertainty for selected experimental scenarios. All calculations are implemented and made available within the Monte Carlo framework McMule.
