In this paper, we analytically compute all master integrals for one of the two non-planar integral families for five-particle massless scattering at two loops. We first derive an integral basis of 73 integrals with constant leading singularities. We... Read More about Analytic result for the nonplanar hexa-box integrals.

Pentagon functions for massless planar scattering amplitudes (2018)
Journal Article
Gehrmann, T., Henn, J., & Lo Presti, N. (2018). Pentagon functions for massless planar scattering amplitudes. Journal of High Energy Physics, 2018(10), Article 103. https://doi.org/10.1007/jhep10%282018%29103

Loop amplitudes for massless five particle scattering processes contain Feynman integrals depending on the external momentum invariants: pentagon functions. We perform a detailed study of the analyticity properties and cut structure of these function... Read More about Pentagon functions for massless planar scattering amplitudes.
