New results for 5-point functions
J. Gluza, T. Riemann
Bhabha scattering is one of the processes at the ILC where high precision data will be expected. The complete NNLO corrections include radiative loop corrections, with contribution…
Virtual Hadronic and Leptonic Contributions to Bhabha Scattering
Stefano Actis, Michal Czakon, Janusz Gluza +1
Using dispersion relations, we derive the complete virtual QED contributions to Bhabha scattering due to vacuum polarization effects in photon propagation. We apply our result to h…
Fermionic NNLO contributions to Bhabha scattering
S. Actis, M. Czakon, J. Gluza +1
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. Convol…
Pentagon diagrams of Bhabha scattering
J. Fleischer, J. Gluza, K. Kajda +1
We report on tensor reduction of five point integrals needed for the evaluation of loop-by-loop corrections to Bhabha scattering. As an example we demonstrate the calculation of th…
Automatizing the application of Mellin-Barnes representations for Feynman integrals
J. Gluza, F. Haas, K. Kajda +1
Feynman diagrams may be evaluated by Mellin-Barnes representations of their Feynman parameter integrals in d=4-2\eps dimensions. Recently, the Mathematica toolkit AMBRE has been de…
Two-Loop Fermionic Corrections to Massive Bhabha Scattering
S. Actis, M. Czakon, J. Gluza +1
We evaluate the two-loop corrections to Bhabha scattering from fermion loops in the context of pure Quantum Electrodynamics. The differential cross section is expressed by a small…
