| 英文摘要 | We perform a global effective-field-theory analysis to assess the precision on the determination of the higgs trilinear self-coupling at future lepton colliders. two main scenarios are considered, depending on whether the center-of-mass energy of the colliders is sufficient or not to access higgs pair production processes. low-energy machines allow for similar to 40% precision on the extraction of the higgs trilinear coupling through the exploitation of next-to-leading-order effects in single higgs measurements, provided that runs at both 240/250 gev and 350 gev are available with luminosities in the few attobarns range. a global fit, including possible deviations in other sm couplings, is essential in this case to obtain a robust determination of the higgs self-coupling. high-energy machines can easily achieve a similar to 20% precision through higgs pair production processes. in this case, the impact of additional coupling modifications is milder, although not completely negligible. |
