We survey on-shell and off-shell higher derivative supergravities in dimensions 1≤ D≤ 11.
Various approaches to their construction, including the Noether procedure,(harmonic) …

We show that extremal Kerr black holes are sensitive probes of new physics. Stringy or
quantum corrections to general relativity are expected to generate higher-curvature terms in …

We derive rigorous bounds on corrections to Einstein gravity using unitarity and analyticity of
graviton scattering amplitudes. In D≥ 4 spacetime dimensions, these consistency conditions …

Starting from the three-and four-point amplitudes we determine the R3-terms in the
gravitational effective actions in the Bose, heterotic and type II superstring theories. We …

We study the effect of higher-curvature terms in the string low-energy effective actions on the
maximally symmetric cosmological solutions of the theory, up to corrections quartic in the …

Exact plane wave solutions of d= 10, N= 1 Einstein-Yang-Mills supergravity theory are
presented and their possible modifications in superstring effective theories are examined. It …

In this paper, our focus is on exploring the gauge-invariant basis for bosonic couplings
within the framework of heterotic string theories, specifically examining three-, five-, and …

Abstract We compute the 3-and 4-point scattering amplitudes for gravitons, antisymmetric
tensors, and gauge bosons in the heterotic string model using the covariant path integral …
