TL;DR: In this article, the effects of D-brane instantons in N = 1 supersymmetric compactifications of Type II string theory to four dimensions are discussed. But the focus is on the instanton sector.
Abstract: We review recent progress in determining the effects of D-brane instantons in N=1 supersymmetric compactifications of Type II string theory to four dimensions. We describe the abstract D-brane instanton calculus for holomorphic couplings such as the superpotential, the gauge kinetic function and higher fermionic F-terms. This includes a discussion of multi-instanton effects and the implications of background fluxes for the instanton sector. Our presentation also highlights, but is not restricted to the computation of D-brane instanton effects in quiver gauge theories on D-branes at singularities. We then summarize the concrete consequences of stringy D-brane instantons for the construction of semi-realistic models of particle physics or SUSY-breaking in compact and non-compact geometries.

TL;DR: Using Noether's identities, this paper defined a superpotential with respect to a background for the Einstein Gauss-Bonnet theory of gravity, and showed that its associated conserved charge yields the mass-energy of a D-dimensional Gauss−Bonnet black hole in an anti-de Sitter spacetime.
Abstract: Using Noether's identities, we define a superpotential with respect to a background for the Einstein Gauss–Bonnet theory of gravity. As an example, we show that its associated conserved charge yields the mass-energy of a D-dimensional Gauss–Bonnet black hole in an anti-de Sitter spacetime.

TL;DR: It is shown that hierarchically small vacuum expectation values of the superpotential in supersymmetric theories can be a consequence of an approximate R symmetry.
Abstract: We show that hierarchically small vacuum expectation values of the superpotential in supersymmetric theories can be a consequence of an approximate R symmetry. We briefly discuss the role of such small constants in moduli stabilization and understanding the huge hierarchy between the Planck and electroweak scales.

TL;DR: In this paper, it was shown that the N=1 supersymmetric SU(N) theory with 2N flavors without superpotential has not only the standard Seiberg dual description but also another dual description involving two copies of the so-called T_N theory.
Abstract: We show that the N=1 supersymmetric SU(N) gauge theory with 2N flavors without superpotential has not only the standard Seiberg dual description but also another dual description involving two copies of the so-called T_N theory. This is a natural generalization to N > 2 of a dual description of SU(2) gauge theory with 4 flavors found by Csaki, Schmaltz, Skiba and Terning. We also study dualities of other N=1 SCFTs involving copies of T_N theories. Our duality is the basic operation from which a recently-found web of N=1 dualities obtained by compactifying M5-branes on Riemann surfaces can be derived field-theoretically.
