Pinching rules in the chiral-splitting description of one-loop string amplitudes
Filippo Maria Balli, Alex Edison, Oliver Schlotterer
Loop amplitudes in string theories reduce to those of gauge theories and (super)gravity in their worldline description as the inverse string tension tends to zero. The appeara…

An exercise in Color-Dual Cut Tiling: Supergravity from Positivity
John Joseph M. Carrasco, Alex Edison, Nia Robles Del Pino +1
The BCJ duality between color and kinematics brings two advantages to calculating multi-loop scattering amplitudes. First the number of ordered cuts that need to be performed to fi…
