Celestial soft currents at one-loop and their OPEs
Rishabh Bhardwaj, Akshay Yelleshpur Srikant
Conformally soft operators and their associated soft theorems on the celestial sphere encode the low energy behaviour of bulk scattering amplitudes. They lead to an infinite dimens…

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…
