1202.3780 (Fotis Farakos et al.)

A New Class of Four-Dimensional N=1 Supergravity with Non-minimal
Derivative Couplings
   [PDF]

Fotis Farakos, Cristiano Germani, Alex Kehagias, Emmanuel N. Saridakis
In the N=1 four-dimensional new-minimal supergravity framework, we
supersymmetrise the coupling of the scalar kinetic term to the Einstein tensor.
This coupling, although introduces a non-minimal derivative interaction of
curvature to matter, it does not introduce harmful higher-derivatives. For this
construction, we employ off-shell chiral and real linear multiplets. Physical
scalars are accommodated in the chiral multiplet whereas curvature resides in a
linear one.
