Abstract
In this talk, I review our progresses on probing new physics at the LHC and future colliders by using the Standard Model Effective Field Theory (SMEFT) and beyond. This includes to probe new physics effects in the Higgs boson couplings via leading dimension-6 operators and in the neutral triple gauge couplings (nTGCs) via leading dimension-8 operators. I also discuss the probe of Higgs self-couplings involving the SM Higgs-boson-pair plus a new heavy Higgs boson of the extended Higgs sector via the resonant diHiggs production channels.
在本讲座中，我将回顾我们在大型强子对撞机和未来对撞机上利用标准模型有效场理论（SMEFT）及其他理论探测新物理的进展。这包括通过前导维6算子探测希格斯玻色子耦合中的新物理效应，以及通过前导维8算子探测中性三规耦合（nTGCs）中的新物理效应。我还讨论了希格斯自耦合的探测，其中涉及 SM 希格斯玻色子对，以及通过共振二希格斯生产通道的扩展希格斯部门的新重希格斯玻色子。
