Phys. Rev. Lett. 95, 010408 (2005) [4 pages]Two-Loop Corrections To Bhabha ScatteringReceived 14 January 2005; published 30 June 2005 The two-loop radiative photonic corrections to Bhabha scattering are computed in the leading order of the small electron mass expansion up to the nonlogarithmic term. After including the soft photon bremsstrahlung, we obtain the infrared-finite result for the differential cross section, which can directly be applied to a precise luminosity determination of the present and future e+e- colliders. © 2005 The American Physical Society URL:
