Abstract
Soft and virtual loop photonic contributions to
the second order next-to-leading QED radiative corrections to
Bhabha scattering are calculated with help of the renormalization
group approach. The results are in agreement with earlier
calculations, where other methods were used. Scale dependence
and the present theoretical accuracy of Bhabha cross section
description are discussed.
