### Description

I will present analytic expressions for the two tennis-court integral families relevant to three-loop $2\to2$ scattering processes involving one massive external particle and massless propagators in terms of Goncharov polylogarithms of up to transcendental weight six. Additionally, I will also present analytic expressions for physical kinematics for the ladder-box family and the two tennis-court families in terms of real-valued polylogarithmic functions, making these results well-suited for phenomenological applications. The full calculation, accompanied by all relevant results in computer-readable form, became recently available in arXiv:[2112.14275].
