Generating higher-derivative couplings in N=2 supergravity    [PDF]

Daniel Butter, Sergei M. Kuzenko

Using a recently developed off-shell formulation for general 4D N=2
supergravity-matter systems, we propose a construction to generate higher
derivative couplings. We address here mainly the interactions of tensor and
vector multiplets, but the construction is quite general. For a certain
subclass of terms, the action is naturally written as an integral over 3/4 of
the Grassmann coordinates of superspace.
