A Two-Form Formulation of the Vector-Tensor Multiplet in Central Charge Superspace
Ioseph Buchbinder, Ahmed Hindawi, Burt A. Ovrut
A two-form formulation for the N=2 vector-tensor multiplet is constructed using superfield methods in central charge superspace. The N=2 non-Abelian standard supergauge multiplet i…
Vector-Tensor multiplet in N=2 superspace with central charge
Ahmed Hindawi, Burt A. Ovrut, Daniel Waldram
We use the four-dimensional N=2 central charge superspace to give a geometrical construction of the Abelian vector-tensor multiplet consisting, under N=1 supersymmetry, of one vect…
Soft Supersymmetry Breaking Induced by Higher-Derivative Supergravitation in the Electroweak Standard Model
Ahmed Hindawi, Burt A. Ovrut, Daniel Waldram
We show how spontaneous supersymmetry breaking in the vacuum state of higher-derivative supergravity is transmitted, as explicit soft supersymmetry-breaking terms, to the effective…
Four-Dimensional Higher-Derivative Supergravity and Spontaneous Supersymmetry Breaking
Ahmed Hindawi, Burt A. Ovrut, Daniel Waldram
We construct two classes of higher-derivative supergravity theories generalizing Einstein supergravity. We explore their dynamical content as well as their vacuum structure. The fi…
Higher-Derivative Gravitation in Bosonic and Superstring Theories and a New Mechanism for Supersymmetry Breaking
Ahmed Hindawi, Burt A. Ovrut, Daniel Waldram
A discussion of the number of degrees of freedom, and their dynamical properties, in higher derivative gravitational theories is presented. The complete non-linear sigma model for…
Two-Dimensional Higher-Derivative Supergravity and a New Mechanism for Supersymmetry Breaking
Ahmed Hindawi, Burt A. Ovrut, Daniel Waldram
We discuss the general form of quadratic (1,1) supergravity in two dimensions, and show that this theory is equivalent to two scalar supermultiplets coupled to non-trivial supergra…
