Two-Loop QCD Corrections to the Heavy Quark Form Factors: Axial Vector Contributions
W. Bernreuther, R. Bonciani, T. Gehrmann +4
We consider the Z Q Qbar vertex to second order in the QCD coupling for an on-shell massive quark-antiquark pair and for arbitrary momentum transfer of the Z boson. We present clos…

Two-loop QCD Corrections to the Heavy Quark Form Factors: the Vector Contributions
W. Bernreuther, R. Bonciani, T. Gehrmann +4
We present closed analytic expressions of the electromagnetic vertex form factors for heavy quarks at the two-loop level in QCD for arbitrary momentum transfer. The calculation is…
