Study of the $h\gamma Z$ coupling at the ILC
@article{Aoki2020StudyOT, title={Study of the \$h\gamma Z\$ coupling at the ILC}, author={Yumi Aoki and Keisuke Fujii and Sunghoon Jung and Junghwan Lee and Junping Tian and Hiroshi Yokoya}, journal={arXiv: High Energy Physics - Experiment}, year={2020} }
We study the $h \gamma Z$ coupling, which is a loop induced coupling in the Standard Model (SM), to probe new physics. In a global fit based on the SM Effective Field Theory, measurement of the SM $h \gamma Z$ coupling can provide a very useful constraint, in particular for the precise determination of $hZZ$ and $hWW$ couplings. At the International Linear Collider (ILC), there are two direct ways to study the $h \gamma Z$ coupling: one is to measure the branching ratio of the $h \to \gamma Z…
