Description
Precise predictions for double Higgs production are essential to probe the Higgs self-coupling at future colliders. A major source of theoretical uncertainty arises from the choice of the top-quark mass renormalization scheme, which strongly affects the predicted cross sections at high energy. In my talk, I will discuss the origin of these uncertainties and show that the mass effects follow a systematic, factorised pattern. This structure allows us to resum the dominant logarithmic contributions and substantially reduce the scheme dependence. The improved predictions provide a more reliable baseline for experimental studies of Higgs pair production and enhance the sensitivity to deviations from the Standard Model.
