Two-Loop Vertices in Quantum Field Theory: Infrared Convergent Scalar Configurations
A. Ferroglia, G. Passarino, M. Passera +1
A comprehensive study is performed of general massive, scalar, two-loop Feynman diagrams with three external legs. Algorithms for their numerical evaluation are introduced and disc…

Planar box diagram for the (N_F = 1) 2-loop QED virtual corrections to Bhabha scattering
R. Bonciani, A. Ferroglia, P. Mastrolia +2
In this paper we present the master integrals necessary for the analytic calculation of the box diagrams with one electron loop (N_{F}=1) entering in the 2-loop (α^3) QED virtual c…

The electroweak form factor \hatκ(q^2) and the running of \sin^2 \hatθ_W
A. Ferroglia, G. Ossola, A. Sirlin
Gauge independent form factors ρ^(e; e) and \hatκ^(e; e)(q^2) for Moller scattering at s << m_W^2 are derived. It is pointed out that \hatκ^(e; e) is very different from its counte…
