Measuring the self-interaction of the Higgs boson is a key objective of the LHC, as it provides direct insight into the shape of the Higgs potential and its consistency with the Standard Model prediction. This measurement crucially relies on the study of Higgs boson pair production, a process that is sensitive to the Higgs self-coupling already at leading order.In this talk, I will first review the current status of QCD corrections to Higgs pair production. I will then present a calculation of partial electroweak corrections, arising from Higgs self-interactions and Yukawa couplings. Since this process is loop-induced, the next-to-leading order NLO corrections require the evaluation of two-loop integrals with internal masses, which are not known analytically. I will show how these corrections can be computed numerically using sector decomposition and present phenomenological results.
