OPE for all helicity amplitudes
Journal of High Energy Physics(2015)
摘要
We extend the Operator Product Expansion (OPE) for scattering amplitudes in planar 𝒩=4 SYM to account for all possible helicities of the external states. This is done by constructing a simple map between helicity configurations and so-called charged pentagon transitions . These OPE building blocks are generalizations of the bosonic pentagons entering MHV amplitudes and they can be bootstrapped at finite coupling from the integrable dynamics of the color flux tube. A byproduct of our map is a simple realization of parity in the super Wilson loop picture.
