Abstract There are holographic superconformal theories in all dimensions between two and six which allow arbitrary tree-level four-point functions to be fixed by basic consistency conditions. Although Mellin space is usually the most efficient settin

Abstract We consider type IIB string theory with N D3 branes and various configurations of sevenbranes, such that the string coupling g s is fixed to a constant finite value. These are the simplest realizations of F-theory, and are holographically du

Abstract We combine perturbation theory with analytic and numerical bootstrap techniques to study the critical point of the long-range Ising (LRI) model in two and three dimensions. This model interpolates between short-range Ising (SRI) and mean-fie

Abstract We consider gluons scattering in Type IIB string theory on AdS5 × S 5 /ℤ2 in the presence of D7 branes, which is dual to the flavor multiplet correlator in a certain 4d N $$ \mathcal{N} $$ = 2 USp(2N) gauge theory with SO(8) flavor symmet

Abstract We provide evidence for the existence of non-trivial unitary conformal boundary conditions for a three-dimensional free scalar field, which can be obtained via a coupling to the m’th unitary diagonal minimal model. For large m we can demon

Abstract We present a systematic study of holographic correlators in a vast array of SCFTs with non-maximal superconformal symmetry. These theories include 4d N $$ \mathcal{N} $$ = 2 SCFTs from D3-branes near F-theory singularities, 5d Seiberg except

Abstract Recently four-point holographic correlators with arbitrary external BPS operators were constructively derived in [1, 2] at tree-level for maximally superconformal theories. In this paper, we capitalize on these theoretical data, and perform

Abstract We study conformal boundary conditions for the theory of a single real scalar to investigate whether the known Dirichlet and Neumann conditions are the only possibilities. For this free bulk theory there are strong restrictions on the possib

A common feature of tree-level holography is that a correlator in one theory can serve as a generating function for correlators in another theory with less continuous symmetry. This is the case for a family of 4d CFTs with eight supercharges which ha

Abstract The existence of an exactly marginal deformation in a conformal field theory is very special, but it is not well understood how this is reflected in the allowed dimensions and OPE coefficients of local operators. To shed light on this questi
