\(\mathcal{N} = 2\) Supergravity and Harmonic Superspace: Linearized Supercurvatures
Using the formulation of \(\mathcal{N} = 2\) supergravity in harmonic superspace, we construct a complete set of linearized supercurvatures that are \(\mathcal{N} = 2\) supersymmetrizations of the scalar curvature, the irreducible part of the Ricci tensor and the self-dual Weyl tensor. Based on these supercurvatures, the total set of quadratic invariants of the linearized \(\mathcal{N} = 2\) supergravity is constructed. Supercurvaturies have a beautiful geometric structure and admit a generalization to higher spins, thereby opening the way towards the construction of a number of \(\mathcal{N} = 2\) supersymmetric cubic interactions of such spins.
期刊介绍:
The journal Fizika Elementarnykh Chastits i Atomnogo Yadr of the Joint Institute for Nuclear Research (JINR, Dubna) was founded by Academician N.N. Bogolyubov in August 1969. The Editors-in-chief of the journal were Academician N.N. Bogolyubov (1970–1992) and Academician A.M. Baldin (1992–2001). Its English translation, Physics of Particles and Nuclei, appears simultaneously with the original Russian-language edition. Published by leading physicists from the JINR member states, as well as by scientists from other countries, review articles in this journal examine problems of elementary particle physics, nuclear physics, condensed matter physics, experimental data processing, accelerators and related instrumentation ecology and radiology.
