This review aims to offer a pedagogical introduction to the analytic conformal bootstrap
program via a journey through selected topics. We review analytic methods which include …

The double copy is, in essence, a map between scattering amplitudes in a broad variety of
familiar field and string theories. In addition to the mathematically rich intrinsic structure, it …

We extend the cosmological bootstrap to correlators involving massless particles with spin.
In de Sitter space, these correlators are constrained both by symmetries and by locality. In …

A bstract We develop a Mellin space approach to boundary correlation functions in anti-de
Sitter (AdS) and de Sitter (dS) spaces. Using the Mellin-Barnes representation of correlators …

A bstract We propose a Mellin space approach to the evaluation of late-time momentum-
space correlation functions of quantum fields in (d+ 1)-dimensional de Sitter space. The …

A bstract We develop the embedding formalism for conformal field theories, aimed at doing
computations with symmetric traceless operators of arbitrary spin. We use an indexfree …

In this paper we take the first steps towards bridging the gap between the conformal and
cosmological bootstrap programs. We present a simple general relation between tree-level …

A bstract We give a detailed account of the methods introduced in [1] to calculate
holographic four-point correlators in IIB supergravity on AdS 5× S 5. Our approach relies …

We study the analytic properties of tree-level wavefunction coefficients in quasi-de Sitter
space. We focus on theories which spontaneously break dS boost symmetries and can …

A bstract In flat space, the color/kinematics duality states that perturbative Yang-Mills
amplitudes can be written in such a way that kinematic numerators obey the same Jacobi …
