The Z' reconsidered
A. Ferroglia, A. Lorca, J. J. van der Bij
We consider the extension of the standard model with an arbitrary number of U(1) gauge fields coupled to baryon-minus-lepton number and/or hypercharge. Under the assumption that A^…
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…
