dSIBP: a package for generating IBP seeds for QFT in de Sitter spacetime
Jiaqi Chen, Yi-Xiao Tao
Recent studies show that in addition to the flat spacetime, Integration-by-parts (IBP) relations and differential equations can also provide a systematic approach to Feynman integr…
Inverse KLT kernel of AdS string integrals from the intersection matrix
Yi-Xiao Tao, Yi-xiao Tao, Shijie Zhang
We develop a topological and combinatorial interpretation of the Kawai--Lewellen--Tye (KLT) relations for -point AdS string-amplitude building blocks, which are disk integrals w…
Off-shell recursion for all-loop planar integrands in Yang-Mills theory
Yi-Xiao Tao
In this paper, we develop in detail the off-shell recursion for planar loop integrands in Yang-Mills theory. Starting from the classical equations of motion solved with the perturb…
Loop integrals in de Sitter spacetime: The parity-split IBP system and -form differential equations
Jiaqi Chen, Bo Feng, Zhehan Qin +1
We develop integration-by-parts (IBP) reduction and differential equations for massive loop integrals of cosmological correlators in de Sitter (dS) spacetime, demonstrating the fea…
Manifest Moebius invariance of massive tree-level three-point amplitudes in pure spinor superspace
Chen Huang, Carlos R. Mafra, Yi-Xiao Tao
Using BRST cohomology properties in pure spinor superspace and identities for OPE brackets of non-free fields, we obtain a new compact nested-bracket representation of massive tree…
Berends-Giele currents for extended gravity
Yi-Xiao Tao
In this short paper, we write down the Berends-Giele (BG) currents for extended gravity explicitly and discuss the unifying relations of these BG currents. This new tool, different…
