Abstract
Radiative corrections due to pair production in process of electron-positro n annihilation are considered. The main attention is paid to the correction s of the third order. Simultaneous emission of photons and pairs is taken i nto account. The leading log approximation and convolution procedure are us ed. Exponentiation is discussed. Theoretical uncertainty in description of higher order secondary pairs is estimated.
