Abstract A new event generator is proposed for two processes e^+ e^- →νν̄γ and e^+ e^- →νν̄γγ where νν̄ includes all the neutrino species. The exact matrix elements of single- and double-photon emission, generated by the GRACE system, are convoluted with the QED parton shower (QEDPS) to deal with the initial state radiations (ISR). It is pointed out that a careful treatment is required to avoid the double counting of the radiative photons between the matrix elements and the ISR part. A detailed compar...
