摘要:

未来的引力波观测在出现一阶电弱相变时,可能对希格斯势的新物理修正敏感。我们研究了SMEFT维度六算符对希格斯势的影响,其中考虑了三种类型的效果:(i)SMEFT树级对$φ^6$算符的影响,(ii)SMEFT树级对希格斯场波函数重整化的影响,以及(iii)SMEFT顶夸克单圈级影响。通过执行Fisher矩阵分析,数值计算了未来引力波观测对这些效应的灵敏度。我们发现,一旦一阶电弱相变由(i)引起,未来的引力波观测可以对(ii)和(iii)敏感。还讨论了维度八$φ^8$算符对一阶电弱相变的影响。未来引力波观测的灵敏度也与未来对撞机实验的灵敏度进行了比较。

英文摘要:

Future gravitational wave observations are potentially sensitive to new physics corrections to the Higgs potential once the first-order electroweak phase transition arises. We study the SMEFT dimension-six operator effects on the Higgs potential, where three types of effects are taken into account: (i) SMEFT tree level effect on $φ^6$ operator, (ii) SMEFT tree level effect on the wave function renormalization of the Higgs field, and (iii) SMEFT top-quark one-loop level effect. The sensitivity of future gravitational wave observations to these effects is numerically calculated by performing a Fisher matrix analysis. We find that the future gravitational wave observations can be sensitive to (ii) and (iii) once the first-order electroweak phase transition arises from (i). The dimension-eight $φ^8$ operator effects on the first-order electroweak phase transition are also discussed. The sensitivities of the future gravitational wave observations are also compared with those of future collider experiments.
