| Abstract: | A calculation of the neutrino counting reaction (e^ + e^ - to vbar vy) is presented and implemented in a Monte Carlo generator of unweighted events. The non-photonic corrections are included following the star-scheme. The photonic corrections have been exponentiated following the “inductive” and the “structure functions” approach. For a realistic experimental set-up, the total corrections around theZ 0 pole amount to ～5% with respect to the one-loop result. The final precision achieved is better than 1%. |
