Résumé |
Production of a pair of Higgs bosons plays a central role in probing the Higgs self-coupling at the LHC. Recent projections from the European Strategy for Particle Physics indicate that this process is expected to be discovered at the HL-LHC, motivating its detailed study. In this talk, we present recent progress on di-Higgs productions, focusing on its theoretical uncertainties. Currently the process is known to N3LO+N3LL in the heavy-top limit, and to NLO QCD and NLO EW with exact top-quark mass dependence. The remaining dominant theoretical uncertainty arises from the choice of quark mass renormalisation scheme and scale. We will discuss progress towards understanding the effect of these quark mass corrections to leading power in the high energy limit. |
