Electroweak corrections to Higgs boson pair production: The light quark case — Marco Bonetti1, Gudrun Heinrich2, •Philipp Rendler2, and William J.

We present a fully analytic computation of the electroweak corrections to Higgs-boson pair production mediated by light quarks in both the gluon and quark-antiquark channels. The calculation is performed using the method of differential equations, employing a large mass expansion to generate boundary functions. We implement the results in the POWHEG BOX framework for phenomenological studies. The corrections to the differential cross section are found to be sizable, reaching up to -30% in the gluon channel and +10% in the quark channel near the production threshold. The quark channel has not been considered before in calculations of the NLO electroweak corrections to Higgs-boson pair production.
