在双Higgs偶重态模型中研究了最轻CP偶Higgs玻色子自耦合常数的单圈修正。在重正化后，有效耦合中可以出现重粒子质量的四次贡献。我们发现，这些非解耦效应可以产生O（100）%的偏差，从标准模型的预测，即使所有其他耦合的最轻的希格斯玻色子规范玻色子和费米子是在良好的协议与标准模型。
One-loop corrections to the self-coupling constant of the lightest CP-even Higgs boson are studied in the two Higgs doublet model. After renormalization is performed, quartic contributions of heavy particle's mass can appear in the effective coupling. We find that these non-decoupling effects can yield O (100) % deviations from the Standard Model prediction, even when all the other couplings of the lightest Higgs boson to gauge bosons and fermions are in good agreement with the Standard Model.
