Web20 okt. 2024 · We extend the Mellin representation of conformal field theory (CFT) to allow for conformal boundaries and interfaces. We consider the simplest holographic setup … Web6 aug. 2024 · Perturbative Mellin representation readily follows. We discuss the main properties of nonperturbative CFT Mellin amplitudes: subtractions, analyticity, unitarity, Polyakov conditions and polynomial boundedness at infinity. Mellin amplitudes are particularly simple for large N CFTs and 2D rational CFTs. We discuss these examples …
Mellin Amplitudes: the Scattering Amplitudes of CFT
Web28 sep. 2024 · On the Polyakov-Mellin bootstrap. We elaborate on some general aspects of the crossing symmetric approach of Polyakov to the conformal bootstrap, as recently formulated in Mellin space. This approach uses, as building blocks, Witten diagrams in AdS. We show the necessity for having contact Witten diagrams, in addition to the exchange … http://dr.iiserpune.ac.in:8080/xmlui/handle/123456789/451?show=full fardin eghtedari

Web25 jul. 2016 · We study conformal partial waves (CPWs) in Mellin space with totally symmetric external operators of arbitrary integer spin. The exchanged spin is arbitrary, … Web5 mei 2024 · We describe in more detail our approach to the conformal bootstrap which uses the Mellin representation of CFT d four point functions and expands them in terms … WebUsing conformal block method we can determine OPE coe cients. Mellin space techniques are more useful than conformal block approach. CFT correlators have nice form in Mellin space. Poles and residues in Mellin amplitude give the information about dimension of factorizing channel and OPE coe - cients. corpus christi library log in
