[HTML][HTML] Selected topics in analytic conformal bootstrap: A guided journey

A Bissi, A Sinha, X Zhou - Physics Reports, 2022 - Elsevier
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 …

Sharp boundaries for the swampland

S Caron-Huot, D Mazáč, L Rastelli… - Journal of High Energy …, 2021 - Springer
A bstract We reconsider the problem of bounding higher derivative couplings in consistent
weakly coupled gravitational theories, starting from general assumptions about analyticity …

Gravitational effective field theory islands, low-spin dominance, and the four-graviton amplitude

Z Bern, D Kosmopoulos… - Journal of Physics A …, 2021 - iopscience.iop.org
We analyze constraints from perturbative unitarity and crossing on the leading contributions
of higher-dimension operators to the four-graviton amplitude in four spacetime dimensions …

AdS bulk locality from sharp CFT bounds

S Caron-Huot, D Mazáč, L Rastelli… - Journal of High Energy …, 2021 - Springer
A bstract It is a long-standing conjecture that any CFT with a large central charge and a large
gap∆ gap in the spectrum of higher-spin single-trace operators must be dual to a local …

Dispersive CFT sum rules

S Caron-Huot, D Mazáč, L Rastelli… - Journal of High Energy …, 2021 - Springer
A bstract We give a unified treatment of dispersive sum rules for four-point correlators in
conformal field theory. We call a sum rule “dispersive” if it has double zeros at all double …

From AdS to dS exchanges: Spectral representation, Mellin amplitudes, and crossing

C Sleight, M Taronna - Physical Review D, 2021 - APS
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 …

The inflationary wavefunction from analyticity and factorization

D Meltzer - Journal of Cosmology and Astroparticle Physics, 2021 - iopscience.iop.org
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 …

An analytical toolkit for the S-matrix bootstrap

M Correia, A Sever, A Zhiboedov - Journal of High Energy Physics, 2021 - Springer
A bstract We revisit analytical methods for constraining the nonperturbative S-matrix of
unitary, relativistic, gapped theories in d≥ 3 spacetime dimensions. We assume extended …

Snowmass White Paper: The Analytic Conformal Bootstrap

T Hartman, D Mazac, D Simmons-Duffin… - arXiv preprint arXiv …, 2022 - arxiv.org
The analytic conformal bootstrap is an array of techniques to characterize, constrain, and
solve strongly interacting quantum field theories using symmetries, causality, unitarity, and …

CFT unitarity and the AdS Cutkosky rules

D Meltzer, A Sivaramakrishnan - Journal of High Energy Physics, 2020 - Springer
A bstract We derive the Cutkosky rules for conformal field theories (CFTs) at weak and
strong coupling. These rules give a simple, diagrammatic method to compute the double …
