Planar two-loop master integrals for massive Bhabha scattering: N_f=1 and N_f=2
Stefano Actis, Michal Czakon, Janusz Gluza +1
Recent developments in the computation of two-loop master integrals for massive Bhabha scattering are briefly reviewed. We apply a method based on expansions of exact Mellin-Barnes…
First order radiative corrections to Bhabha scattering in dimensions
J. Fleischer, J. Gluza, A. Lorca +1
The luminosity measurement at the projected International Linear Collider ILC is planned to be performed with forward Bhabha scattering with an accuracy of the order of $1…
The planar four-point master integrals for massive two-loop Bhabha scattering
M. Czakon, J. Gluza, T. Riemann
We present the values of the complete set of planar four-point Master Integrals needed for massive Bhabha scattering in the limit of fixed angle and high energy at the two-loop lev…
Majorana neutrino textures from numerical considerations: the CP conserving case
B. Dziewit, K. Kajda, J. Gluza +1
Phenomenological bounds on the neutrino mixing matrix U are used to determine numerically the allowed range of real elements (CP conserving case) for the symmetric neutrino mass ma…
Differential equations and massive two-loop Bhabha scattering: the B5l2m3 case
M. Czakon, J. Gluza, K. Kajda +1
The two-loop box contributions to massive Bhabha scattering may be reduced to two-loop box master integrals (MIs) with five, six, and seven internal lines, plus vertices and self e…
