Abstract

An original matching procedure of the Parton Shower approach to Bhabha process with the complete exact \( \mathcal{O} \) (α) matrix elements is discussed, in relation to high-precision luminosity determination at flavour factories. For this purpose, a new version of BABAYAGA event generator has been released, with a theoretical error reduced down to 0.1%, as estimated by comparison with independent calculations.
