Supersymmetric gyratons in five dimensions / Marco M. Caldarelli, Dietmar Klemm, Emanuele Zorzan. - In: CLASSICAL AND QUANTUM GRAVITY. - ISSN 0264-9381. - 24:5(2007 Mar 07), pp. 016.1341-016.1357.
Abstract:
We obtain the gravitational and electromagnetic field of a spinning radiation beam-pulse (a gyraton) in minimal five-dimensional gauged supergravity and show under which conditions the soln. preserves part of the supersymmetry. The configurations represent generalizations of Lobatchevski waves on AdS with nonzero angular momentum, and possess a Siklos-Virasoro reparametrization invariance. We compute the holog. stress-energy tensor of the solns. and show that it transforms without anomaly under these reparametrizations. Furthermore, we present supersym. gyratons both in gauged and ungauged five-dimensional supergravity coupled to an arbitrary no. of vector supermultiplets, which include gyratons on domain walls.
