摘要

We present a semi-analytic calculation of the integrated double-emission eikonal function of two massive emitters whose momenta are at an arbitrary angle to each other. This result is needed for extending the nested soft-collinear subtraction scheme [Eur. Phys. J. C 77 (2017) 248] to processes with massive partons.
