Abstract：
We propose to measure the HZγ and Hγγ anomalous couplings in the process e⁺e^-→Hγ with the sequential decay of H→bb. The discovery potential of observing the anomalous couplings are explored in detail. Our study shows that future electron-positron colliders have great potential to test the HZγ and Hγγ couplings. Conservative bounds on the two anomalous couplings are also derived when no new physics signal is detected on top of the SM backgrounds.
- Higgs physics ,
- rare decay ,
- electron-positron collision
