(8,0) locally supersymmetric sigma models with conformal invariance in two dimensions (1987)
Sezgin, E., Bergshoeff, E., Nishino, H.
The (8,0) conformal supergravity, and an action which describes its coupling to an arbitrary number of (8,0) scalar multiplets are constructed. The 64+64 components of the conformal supermultiplet...
The Born-Infeld action from conformal invariance of the open superstring (1987)
Townsend, P.K., Pope, C.N., Sezgin, E., Bergshoeff, E.
We show that the one-loop approximation to sigma-model perturbation theory for the open-superstring leads to the low-energy effective action of Born-Infeld for the gauge field coupled to the ends of...
Supermembranes and eleven-dimensional supergravity (1987)
Townsend, P.K., Sezgin, E., Bergshoeff, E.
We construct an action for a supermembrane propagating in d=11 supergravity background. Using the constraints of d=11 curved superspace, we show that the action is invariant under Siegel-type...
Supersymmetric supermembrane vacua and singletons (1987)
Sezgin, E., Pope, C.N., Duff, M.J., Bergshoeff, E.
The eleven-dimensional supermembrane exhibits a local world-volume Siegel symmetry provided the spacetime background is a solution of D=11 supergravity. If this background admits Killing spinors the...
Superconformal tensor calculus and matter couplings in six dimensions (1986)
Proeyen, A. Van, Sezgin, E., Bergshoeff, E.
Using superconformal tensor calculus we construct general interactions of N = 2, d = 6 supergravity with a tensor multiplet and a number of scalar, vector and linear multiplets. We start from the...
Sarmadi, H., Salam, A., Randjbar-Daemi, S., Bergshoeff, E., Sezgin, E.
We construct an N = 1 locally supersymmetric σ-model with a Wess-Zumino term coupled to supergravity in two dimensions. If one takes the σ-model manifold to be the product of d-dimensional...
Heterotic σ-models and conformal supergravity in two dimensions (1986)
Sezgin, E., Bergshoeff, E., Nishino, H.
The (1, 0) and (2, 0) type heterotic σ-models with Wess-Zumino term are coupled to conformal supergravity in two dimensions. There are no new restrictions on the σ-model manifolds in addition to...
Superstring actions in D = 3,4,6,10 curved superspace (1986)
Townsend, P.K., Sezgin, E., Bergshoeff, E.
The constraints on the supergeometry of D = 3,4,6,10 curved superspace, required for the coupling of supergravity to the Green-Schwarz superstring, are determined. We show that these are consistent...
A supersymmetric R2-action in six dimensions and torsion (1986)
Salam, Abdus, Bergshoeff, E., Sezgin, E.
The superconformal extension of (Rµνab)2 is given in six dimensions. It is shown that in a superconformal gauge the three-form field Hµνρ has a natural torsion interpretation. Also partial...
Coupling of Yang-Mills to N = 4, d = 4 supergravity (1985)
Koh, I.G., Bergshoeff, E., Sezgin, E.
We couple N = 4, d = 4 supersymmetric Yang-Mills theory to supergravity. The scalars of the theory parametrize the coset (SO(n,6)/[SO(n)×SO(6)])×(SU(1,1)/U(1)). Keeping the composite local...
Yang-Mills-Einstein supergravity in seven dimensions (1985)
Koh, I.G., Bergshoeff, E., Sezgin, E.
We construct couplings of n vector multiplets to seven-dimensional N=2 supergravity. The 3n scalars of the theory parametrize the coset SO(n,3)/SO(n)×SO(3). The (n+3) vector fields are used to gauge...
