# The dipole formula The **dipole formula** is a conjecture stating that the [[0009 Soft theorems|soft]] and [[0078 Collinear limit|collinear]] singularities exponentiate such that the exponents contains colour correlations between at most pairs of external legs. This seems useful in trying to formulate something of a [[0198 Celestial double copy]] where we want to see the [[0067 Double copy]] structure appearing in the [[0114 Celestial OPE]]. ## Related topics - [[0067 Double copy]] - [[0198 Celestial double copy]] ## Refs - [[2008#Dixon, Magnea, Sterman]] - [[BecherNeubert200901]] - [[BecherNeubert200903]] - [[GardiMagnea200901]] - [[GardiMagnea200908]]
