چکیده

We review the status of the calculation of next-to-next-to-leading order corrections to large angle Bhabha scattering in pure QED. After discussing the electron-loop and photonic corrections, we focus on the recently calculated two-loop virtual corrections involving a heavy-flavor fermion loop. We conclude by assessing the numerical impact of these corrections on the Bhabha scattering cross section at colliders operating at a center of mass energy of about 1-GeV.

Fermionic NNLO contributions to Bhabha Scattering

We derive the two-loop corrections to Bhabha scattering from heavy fermions using dispersion relations. The double-box contributions are expressed by three kernel functions. Convoluting the perturbative kernels with fermionic threshold functions or with hadronic data allows to determine numerical results for small electron mass m e , combined with arbitrary values of the fermion mass m f in the...

Two-loop QED Corrections to Bhabha Scattering

Bhabha scattering, ee → ee, is a crucial process in the phenomenology of particle physics. Its relevance is mainly due to the fact that it is the process employed to determine the luminosity L at ee colliders: in fact, L = NBhabha/σth, where NBhabha is the rate of Bhabha events and σth is the Bhabha scattering cross section calculated from theory. Two kinematic regions are of special interest f...

Decays at NNLO in SCET

We compute NNLO (O(α2 s)) corrections to the hard-scattering kernels entering the QCD factorization formula for B → V γ decays, where V is a light vector meson. We give complete NNLO results for the dipole operators Q7 and Q8, and partial results for Q1 valid in the large-β0 limit and neglecting the NNLO correction from hard spectator scattering. Large perturbative logarithms in the hard-scatte...

Investigation of vacuum polarization in t-channel radiative Bhabha scattering

We discuss the possibility of a precision measurement of vacuum polarization in t-channel radiative Bhabha scattering at a high luminosity collider. For illustration, the achievable precision is estimated for the BaBar experiment at PEP-II and for the OPAL experiment at LEP.
