Magnetic mass in 4D AdS gravity
(2016)
We provide a fully covariant expression for the diffeomorphic charge in four-dimensional anti-de Sitter gravity, when the Gauss-Bonnet and Pontryagin terms are added to the action. The couplings of these topological ...
Duality of parity doublets of helicity +/- 2 in D=2+1 dimensions
(Amer Physical Soc, 2010-11-10)
In D = 2 + 1 dimensions there are two dual descriptions of parity singlets of helicity +/-1, namely, the self-dual model of first order (in derivatives) and the Maxwell-Chern-Simons theory of second order. Correspondingly, ...
Unitarity of spin-2 theories with linearized Weyl symmetry in D=2+1 dimensions
(Amer Physical Soc, 2009-10-01)
Here we prove unitarity of the recently found fourth-order (in derivatives) self-dual model of spin-2 by investigating the analytic structure of its propagator. The model describes massive particles of helicity +2 (or -2) ...
Manifest electromagnetic duality in closed superstring field theory
(Elsevier B.V., 1996-11-28)
The free action for massless Ramond-Ramond fields is derived from closed superstring field theory using the techniques of Siegel and Zwiebach. For the uncompactified Type IIB superstring, this gives a manifestly Lorentz-covariant ...
Superstrings in graviphoton background and N=1/2+3/2 supersymmetry
(Int School Advanced Studies, 2003-07-01)
Motivated by Ooguri and Vafa, we study superstrings in flat R-4 in a constant self-dual graviphoton background. The supergravity equations of motion are satisfied in this background which deforms the N = 2 d = 4 flat space ...
T-duality of axial and vector dyonic integrable models
(Academic Press Inc., 2001-05-01)
A general construction of affine nonabelian (NA)-Toda models in terms of the axial and vector gauged two loop WZNW model is discussed. They represent integrable perturbations of the conformal sigma -models (with tachyons ...
Duality-symmetric eleven-dimensional supergravity and its coupling to M-branes
(1998-06-29)
The standard eleven-dimensional supergravity action depends on a three-form gauge field and does not allow direct coupling to five-branes. Using previously developed methods, we construct a covariant eleven-dimensional ...
Local actions with electric and magnetic sources
(1997-03-06)
Superstring field theory was recently used to derive a covariant action for a self-dual five-form field strength. This action is shown to be a ten-dimensional version of the McClain-Wu-Yu action. By coupling to D-branes, ...
Superstrings in graviphoton background and N = 1/2 + 3/2 supersymmetry
(2003-07-01)
Motivated by Ooguri and Vafa, we study superstrings in flat ℝ4 in a constant self-dual graviphoton background. The supergravity equations of motion are satisfied in this background which deforms the M = 2 d = 4 flat space ...
