A double copy from twisted (co)homology at genus one
Rishabh Bhardwaj, Andrzej Pokraka, Lecheng Ren +1
We study the twisted (co)homology of a family of genus-one integrals -- the so called Riemann-Wirtinger integrals. These integrals are closely related to one-loop string amplitudes…
One-loop Integrals from Volumes of Orthoschemes
Lecheng Ren, Marcus Spradlin, Cristian Vergu +1
Recently in arXiv:2012.05599 Rudenko presented a formula for the volume of hyperbolic orthoschemes in terms of alternating polylogarithms. We use this result to provide an explicit…
All-order celestial OPE from on-shell recursion
Lecheng Ren, Anders Schreiber, Atul Sharma +1
We determine tree level, all-order celestial operator product expansions (OPEs) of gluons and gravitons in the maximally helicity violating (MHV) sector. We start by obtaining the…
