Abstract:

Lowest order radiative correction to the Bhabha scattering, e⁺e^- →e⁺e^-, is calculated in the standard electroweak theory. The real and hard photon emission is included so as to satisfy a realistic experimental condition. The corrected differential cross sections, ( dσ/dΩ)_{ζ< ζ_c,q_±0 > E_th}, are given at √s=70,93 and 150 GeV. An acollinearity angle cut, ζ_c=10°, and a threshold energy cut, E_th=20 GeV, for the energies of the final e⁺ and e^-, q₊₀ and q_-0, are imposed. The energy spectrum of scattered positron at fixed angle, dσ/ dq₊₀ dcos θ, is also given which will be helpful for luminosity measurement of the colliding beams or background estimation due to radiatibe Bhabha scattering.
