Phase space master integrals for N³LO Higgs boson production — Chihaya Anzai¹, •Maik Höschele¹, and Takahiro Ueda² — ¹KIT, 76128 Karlsruhe, Germany — ²Nikhef, 1098 XG Amsterdam, Netherlands

Master integrals needed for Higgs boson production in gluon fusion are computed using the method of differential equations. We apply the recently proposed method to transform the system of differential equations to a canonical form which simplifies its integration. We discuss in detail our strategy to obtain the transformation matrices and explain our method used for the evaluation of the initial conditions. Finally, non-trivial results are shown.
