The Levi-Civita tensor noncovariance and curvature in the pseudotensors space
A. L. Koshkarov
It is shown that conventional "covariant" derivative of the Levi-Civita tensor is not really covariant. Adding compensative terms, it is possible to make it covariant and to be equ…

Two-Loop Formfactors in Theories with Mass Gap and Z-Boson Production
A. Kotikov, J. H. Kuhn, O. Veretin
The two-loop formfactor both for a U(1)xU(1) and a SU(2)xU(1) gauge theory with massive and massless gauge bosons respectively is evaluated at arbitrary momentum transfer q^2. The…
