Description
Bootstrapping techniques---wherein one imposes known constraints on an ansatz in the hope of uniquely determining the answer---have proven to be an increasingly powerful method for computing amplitudes in recent years. While the most significant progress in this direction has been made in planar maximally supersymmetric Yang- Mills theory, these techniques can be naturally extended to the types of quantities directly relevant to collider computations. One place these methods show particular promise is in the resummation of large logarithms, and we here report the successful bootstrap of the (correction to the all-order dipole contribution) of the massless soft anomalous dimension at three loops, up to an overall numerical factor.
