The Elliptic Double-Box Integral: Massless Amplitudes Beyond Polylogarithms
Jacob L. Bourjaily, Andrew J. McLeod, Marcus Spradlin +2
We derive an analytic representation of the ten-particle, two-loop double-box integral as an elliptic integral over weight-three polylogarithms. To obtain this form, we first deriv…
Prescriptive Unitarity
Jacob L. Bourjaily, Enrico Herrmann, Jaroslav Trnka
We introduce a prescriptive approach to generalized unitarity, resulting in a strictly-diagonal basis of loop integrands with coefficients given by specifically-tailored residues i…
The Conformal BMS Group
Sasha J. Haco, Stephen W. Hawking, Malcolm J. Perry +1
We describe the conformal symmetries of asymptotically flat spacetime. These represent an extension of the BMS group that we call the conformal BMS group. Its general features are…
