摘要：

A study of the radiative neutrino-counting reaction e(+)e(-) --> $($) over bar$$ vvy at LEP1 and LEP2 energies is presented. An approximate expression for the spectrum of the observed photon is derived within the framework of the p(t)-dependent structure function approach, This is compared with an exact expression and found to be in agreement within the foreseen experimental accuracy. This model describing single-photon radiation can be applied to the more general case of initial-state single-photon emission accompanying invisible final-state events. Higher-order QED corrections due to undetected initial-state radiation are also included, The implementation in a Monte Carlo event generator is briefly described.
