Description

The infrared exponentiation properties of dimensionally-regularized multi-loop scattering amplitudes are typically hidden at the level of the integrand, materializing only after integral evaluation. In this talk, we provide evidence that this long-standing problem may be addressed by introducing an appropriate integral basis which is simultaneously finite and uniform weight.
