Description
We present a fully analytic computation of the two-loop electroweak corrections to double Higgs production in gluon fusion, mediated by light quarks. 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-V2 framework for phenomenological studies. The corrections to the differential cross section are found to be sizable, reaching up to $-15\%$ near the production threshold. Additionally, we investigate the sensitivity of these corrections to variations of the triple Higgs self-coupling $\lambda_{HHH}$.
