Critical and Non-Critical Einstein-Weyl Supergravity
H. Lu, C. N. Pope, E. Sezgin +1
We construct N=1 supersymmetrisations of some recently-proposed theories of critical gravity, conformal gravity, and extensions of critical gravity in four dimensions. The total ac…
Pseudo-Supergravity Extension of the Bosonic String
H. Lu, C. N. Pope, Zhao-Long Wang
We construct a ``pseudo-supersymmetric" fermionic extension of the effective action of the bosonic string in arbitrary spacetime dimension D. The theory is invariant under pseudo-s…
Conformal Gravity and Extensions of Critical Gravity
H. Lu, Yi Pang, C. N. Pope
Higher-order curvature corrections involving the conformally-invariant Weyl-squared action have played a role in two recent investigations of four-dimensional gravity; in critical…
Pseudo-supersymmetry, Consistent Sphere Reduction and Killing Spinors for the Bosonic String
H. Lu, C. N. Pope, Zhao-Long Wang
Certain supergravity theories admit a remarkable consistent dimensional reduction in which the internal space is a sphere. Examples include type IIB supergravity reduced on S^5, an…
Critical Points of D-Dimensional Extended Gravities
S. Deser, Haishan Liu, H. Lu +3
We study the parameter space of D-dimensional cosmological Einstein gravity together with quadratic curvature terms. In D>4 there are in general two distinct (anti)-de Sitter vacua…
Critical Gravity in Four Dimensions
H. Lu, C. N. Pope
We study four-dimensional gravity theories that are rendered renormalisable by the inclusion of curvature-squared terms to the usual Einstein action with cosmological constant. By…
