Abstract

摘要

By using a double-cover approach to the CHY formulation, we will present in this talk a set of rules to build integrands on a genus one Riemann surface by introducing a set of "connectors" that generalizes the propagator $1/z_{ab}$ over the sphere. We will show how this rules will lately allow us to compute scattering amplitudes at one-loop and also will comment on the possible extensions to higher loops.
