The $H\gamma$ final state at FCC-ee

This work investigates the $H\gamma$ final state in collisions at the FCC-ee, housing an electron-positron collider. The events reconstruction is based on the IDEA detector concept.The final state in question relies on loop-based production and provides insight in the effective $H\gamma\gamma$ and $H\gamma Z$ coupling. The presented analysis is based on the recoil mass method and does not apply an explicit Higgs selection. The final measurement precision is evaluated by a cut \& count analysis as well as a likelihood fit on the photon recoil mass. Both results are compatible with a precision of 228\% and 234\%, respectively.
