论文摘要
我们使用有效的现场理论（EFT）方法来评估希格斯的生存能力，以解释$ G-2 $异常。 Although the SM contribution of the Higgs to the muon's magnetic dipole moment is negligible, using a \textit{bottom-up} EFT, we show that given the current level of experimental limits on the Higgs sector, the Higgs can still yield a viable solution to the $g-2$ anomaly if its couplings to the rest of the SM particles are allowed to deviate from their SM predictions.此外，应用单位性论点，我们表明，这样的解决方案将表明$ \ sim 10 -18 $ tev的新物理（NP）的比例，如果假定Higgs耦合到$ W $，则可以将其降低至$ \ sim 5 $ TEV，并假定$ Z $与他们的SM预测相符。我们表明，这种情况可能会为MUON COLLIDERS中的Di-Higgs生产带来重大增强，从而为其考虑提供了进一步的动力。这项研究的关键要点是强调在未来实验中测量$ \barμHH$耦合的重要性。
We use an Effective Field Theory (EFT) approach to evaluate the viability of the Higgs to account for the $g-2$ anomaly. Although the SM contribution of the Higgs to the muon's magnetic dipole moment is negligible, using a \textit{bottom-up} EFT, we show that given the current level of experimental limits on the Higgs sector, the Higgs can still yield a viable solution to the $g-2$ anomaly if its couplings to the rest of the SM particles are allowed to deviate from their SM predictions. Further, applying unitarity arguments, we show that such a solution would indicate a scale of New Physics (NP) of $\sim 10 -18$ TeV, which could be lowered to $\sim 5$ TeV if the Higgs couplings to the $W$ and $Z$ are assumed to conform to their SM predictions. We show that such a scenario could yield significant enhancement to the di-Higgs production in muon colliders, thus providing further motivation for its consideration. A key takeaway of this study is to highlight the importance of measuring the $\barμ μhh$ coupling in future experiments.
