Monitoring a de Sitter universe through an anti-de Sitter window
Sarah Hoback, Daniel L. Jafferis, Zixia Wei
We propose that AdS gravity coupled to dS end-of-the-world branes is dual to a unitary holographic CFT with non-unitary conformal boundary conditions. These boundary co…
Formalization of QFT
Michael R. Douglas, Sarah Hoback, Anna Mei +1
A foundational result in constructive quantum field theory is the construction of the free bosonic quantum field theory in four-dimensional Euclidean spacetime and the proof that i…
Feynman Rules for Scalar Conformal Blocks
Jean-François Fortin, Sarah Hoback, Wen-Jie Ma +2
We complete the proof of "Feynman rules" for constructing -point conformal blocks with external and internal scalars in any topology for arbitrary in any spacetime dimension…
Dimensional reduction of higher-point conformal blocks
Sarah Hoback, Sarthak Parikh
Recently, with the help of Parisi-Sourlas supersymmetry an intriguing relation was found expressing the four-point scalar conformal block of a (d-2)-dimensional CFT in terms of a f…
Towards Feynman rules for conformal blocks
Sarah Hoback, Sarthak Parikh
We conjecture a simple set of "Feynman rules" for constructing -point global conformal blocks in any channel in spacetime dimensions, for external and exchanged scalar opera…
