Abstract

We study the e+ehγe^+e^-\to h \gamma process at the International Linear Collider (ILC) to probe new physics in the hγZh\gamma Z coupling. The study is performed at a center of mass energy of 250 GeV and is based on the full simulation of the International Large Detector (ILD). The expected signal significance is found to be 0.53 σ\sigma for an integrated luminosity of 2000 fb1^{-1} in the case of the standard model. The corresponding 95 %\% confidence level upper limit for the signal cross section is 1.08 fb for left-handed beam polarization.
