A bstract In this follow up paper, we calculate higher point tree level graviton Witten
diagrams in AdS 4 via bulk perturbation theory. We show that by rearranging the bulk to bulk …

A bstract Conformal blocks are the fundamental, theory-independent building blocks in any
CFT, so it is important to understand their holographic representation in the context of …

A bstract In this paper, we present a simple and iterative algorithm that computes Witten
diagrams. We focus on the gauge correlators in AdS in four dimensions in momentum …

A photocatalytically active bipolar membrane consisting of a CdS photocatalyst and Pd
electrocatalyst has been constructed to carry out environmentally relevant oxidation and …

In this paper, we explore momentum space approach to computing scalar amplitudes in anti–
de Sitter (AdS) space. We show that the algorithm derived by Arkani-Hamed, Benincasa …

A bstract Conformal blocks play a central role in CFTs as the basic, theory-independent
building blocks. However, only limited results are available concerning multipoint blocks …

In this work we present a systematic study of AdS d+ 1 loop amplitudes for gluons and
gravitons using momentum space techniques. Inspired by the recent progress in tree-level …

A bstract We present the holographic object which computes the five-point global conformal
block in arbitrary dimensions for external and exchanged scalar operators. This object is …

A bstract In this paper, we propose a p-adic analog of Mellin amplitudes for scalar operators,
and present the computation of the general contact amplitude as well as arbitrary-point tree …

Given a number field $ K $ with a Hecke character $\chi $, for each place $\nu $ we study
the free scalar field theory whose kinetic term is given by the regularized Vladimirov …
