The Superconformal Gaugings in Three Dimensions
Eric A. Bergshoeff, Olaf Hohm, Diederik Roest +2
We show how three-dimensional superconformal theories for any number N <= 8 of supersymmetries can be obtained by taking a conformal limit of the corresponding three-dimensional ga…
Transverse Symmetry and Spin-3/2 Fields
D. Blas
We study the possible covariant Lagrangians that describe the propagation of pure spin-3/2 particles. We show that, apart from the well-known Rarita-Schwinger Lagrangian, there is…
Enlarged NH symmetries: Particle Dynamics and Gauge Symmetries
Joaquim Gomis, Jerzy Lukierski
We show how the Newton-Hooke (NH) symmetries, representing a nonrelativistic version of de-Sitter symmetries, can be enlarged by a pair of translation vectors describing in Galilea…
Bicycling Black Rings
Henriette Elvang, Maria J. Rodriguez
We present detailed physics analyses of two different 4+1-dimensional asymptotically flat vacuum black hole solutions with spin in two independent planes: the doubly spinning black…
Fundamental Plasmid Strings and Black Rings
Jose J. Blanco-Pillado, Roberto Emparan, Alberto Iglesias
We construct excited states of fundamental strings that admit a semiclassical description as rotating circular loops of string. We identify them with the supergravity solutions for…
Microscopic Theory of Black Hole Superradiance
Oscar J. C. Dias, Roberto Emparan, Alessandro Maccarrone
We study how black hole superradiance appears in string microscopic models of rotating black holes. In order to disentangle superradiance from finite-temperature effects, we consid…
