Probing Effective HZ$\gamma$ Couplings via H$\gamma$ Production at FCC-ee

This work investigates the $e^+e^-\rightarrow H\gamma$ production mode in $\rm{\sqrt{s}}=240 GeV$ collisions at the FCC-ee.
The utilized event reconstruction is based on IDEA, a detector concept study for FCC-ee.

Loops contribute to the production of the $H\gamma$ final state, which provides insight in the effective $H\gamma\gamma$ and $H\gamma Z$ coupling. 
Based on the recoil mass method, the analysis comprises both, an inclusive as well as an exclusive study of the $\mathrm{H}\rightarrow b\bar{b}$ channel.
The final measurement precision is evaluated by a cut & count analysis in comparison with a likelihood fit. 
The inclusive measurement results in an expected precision of 230%.
The exclusive study yields a precision of 150%.
