Extensions of Einstein gravity with higher-order derivative terms arise in string theory and othereffective theories, as well as being of interest in their own right. In this Letter we study static black-holesolutions in the example of Einstein gravity with additional quadratic curvature terms. A Lichnerowicztypetheorem simplifies the analysis by establishing that they must have vanishing Ricci scalar curvature.By numerical methods we then demonstrate the existence of further black-hole solutions over and above theSchwarzschild solution. We discuss some of their thermodynamic properties, and show that they obey thefirst law of thermodynamics.

© Springer-Verlag Berlin Heidelberg 2013. An overview is given of the way in which the unification program of particle physics has evolved into the proposal of superstring theory as a prime candidate for unifying quantum gravity with the other forces and particles of nature. A key concern with quantum gravity has been the problem of ultraviolet divergences, which is naturally solved in string theory by replacing particles with spatially extended states as the fundamental excitations. String theory turns out, however, to contain many more extended-object states than just strings. Combining all this into an integrated picture, called M-theory, requires recognition of the rôle played by a web of nonperturbative duality symmetries suggested by the nonlinear structures of the field-theoretic supergravity limits of string theory.

It is important to test M-theory in regions of the moduli space that cannot be reached by string theory and thus to probe M-theory's intrinsic structure. One such test is the compactification of M-theory on manifolds with SU(5) holonomy, which require ten Euclidean-signature dimensions and hence probe beyond anything that can be discussed in perturbative string theory. We present some preliminary results of ongoing work that is focused on studying the resulting one-dimensional effective action. © 2008 World Scientific Publishing Co. Pte. Ltd.

Stelle KS, 2008, Is N = 8 supergravity an ultraviolet finite quantum field theory?, Pages: 137-141
Advances in the computation of quantum amplitudes in supergravity theories raise the question whether maximal supergravity in D = 4 spacetime dimensions might actually be free of ultraviolet divergences. On the other hand, supersymmetric non-renormalization theorems give no indication of cancellations for anything beyond half-BPS counterterm operators. The jury is still out, and bets are being taken on the outcome.
