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…
Non-Trivial Vacua in Higher-Derivative Gravitation
Ahmed Hindawi, Burt A. Ovrut, Daniel Waldram
A discussion of an extended class of higher-derivative classical theories of gravity is presented. A procedure is given for exhibiting the new propagating degrees of freedom, at th…
Consistent Spin-Two Coupling and Quadratic Gravitation
Ahmed Hindawi, Burt A. Ovrut, Daniel Waldram
A discussion of the field content of quadratic higher-derivative gravitation is presented, together with a new example of a massless spin-two field consistently coupled to gravity.…
Higher-Derivative Gravitation and a New Mechanism for Supersymmetry Breaking in Four-Dimensions
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…
