Electroweak corrections to Higgs boson pair production: The light quark case — •Philipp Rendler, Marco Bonetti, and William J. Torres Bobadilla — Karlsruhe Institute of Technology

We present the two-loop electroweak corrections for double Higgs production in gluon fusion mediated by light quarks. We construct a basis of master integrals that satisfy canonical differential equations in dlog form, employing a large mass expansion to generate boundary functions. The results are expressed in terms of Chen iterated integrals up to weight six over logarithmic kernels with algebraic arguments. We organize the integrals in terms of independent functions, allowing for fast numerical evaluation in the physical region.
