Quark-initiated Double Higgs Production at one loop — •Philipp Rendler — Karlsruhe Institute of Technology

We present the analytic amplitude for double Higgs production in the quark-initiated channel at one loop, with full dependence on all mass scales. The calculation is performed using the method of differential equations employing a large mass expansion to fix the integration constants. The results are written in terms of iterated integrals, with integrals from simpler topologies being expressed in terms of Generalized PolyLogarithms. This amplitude forms a part of the electroweak corrections to Higgs boson pair production.
