Off-Shell Invariants of Linearized 4D, N=2 Supergravity in the Harmonic Approach / E.Ivanov, N.Zaigraev // Physical Review D [Electronic resource]. – 2024. – Vol. 110, No. 6. – P. 066020. – URL: https://doi.org/10.1103/PhysRevD.110.066020. – Bibliogr.: 65.

Using the harmonic superspace approach, we construct, at the linearized level, N=2 supersymmetric curvatures generalizing scalar curvature, Ricci curvature and Weyl tensor. These supercurvatures are the building blocks of various linearized 4D; N=2 Einstein supergravity invariants. The supercurvatures involving the scalar and Ricci curvatures are analytic harmonic N=2 superfields, while the Weyl supertensor is a chiral N=2 superfield. As the basic distinguished feature of our construction, all these objects are expressed through the fundamental analytic gauge prepotentials h&sup(++M), M=(*a*a,*a+,*a+,5). The related characteristic features are the heavy use of harmonic derivatives and harmonic zero-curvature equations. On a number of instructive examples, we describe the component reduction of the superfield invariants constructed.
