On the massive two-loop corrections to Bhabha scattering
M. Czakon, J. Gluza, T. Riemann
We overview the general status of higher order corrections to Bhabha scattering and review recent progress in the determination of the two-loop virtual corrections. Quite recently,…
Harmonic polylogarithms for massive Bhabha scattering
M. Czakon, J. Gluza, T. Riemann
One- and two-dimensional harmonic polylogarithms, HPLs and GPLs, appear in calculations of multi-loop integrals. We discuss them in the context of analytical solutions for two-loop…
ZFITTER: a semi-analytical program for fermion pair production in e+e- annihilation, from version 6.21 to version 6.42
A. B. Arbuzov, M. Awramik, M. Czakon +5
ZFITTER is a Fortran program for the calculation of fermion pair production and radiative corrections at high energy e+e- colliders; it is also suitable for other applications wher…
Master integrals for massive two-loop Bhabha scattering in QED
M. Czakon, J. Gluza, T. Riemann
We present a set of scalar master integrals (MIs) needed for a complete treatment of massive two-loop corrections to Bhabha scattering in QED, including integrals with arbitrary fe…
