Cirilo-Lombardo, Diego Julio; Pervushin, Victor N. Quaternionic (super) twistors extensions and general superspaces. (English) Zbl 1356.81152 Int. J. Geom. Methods Mod. Phys. 14, No. 1, Article ID 1750009, 13 p. (2017). Summary: In an attempt to treat a supergravity as a tensor representation, the four-dimensional \(N\)-extended quaternionic superspaces are constructed from the (diffeomorphic) graded extension of the ordinary Penrose-twistor formulation, performed in a previous work of the authors [Int. J. Geom. Methods Mod. Phys. 13, No. 9, Article ID 1650113, 10 p. (2016; Zbl 1352.32005)], with \(N=p+k\). These quaternionic superspaces have \(4+k(N-k)\) even-quaternionic coordinates and \(4N\) odd-quaternionic coordinates, where each coordinate is a quaternion composed by four \(\mathbb{C}\)-fields (bosons and fermions respectively). The fields content as the dimensionality (even and odd sectors) of these superspaces are given and exemplified by selected physical cases. In this case, the number of fields of the supergravity is determined by the number of components of the tensor representation of the four-dimensional \(N\)-extended quaternionic superspaces. The role of tensorial central charges for any \(N\) even \(U\mathrm{Sp}(N)=\mathrm{Sp}(N,\mathbb{H}_{\mathbb{C}})\cap U(N,\mathbb{H}_{\mathbb{C}})\) is elucidated from this theoretical context.
