摘要：
We explore the prospects to discover the h -> Z gamma decay in t (t) over bar -associated production, featuring a signal-tobackground ratio of O(1). Performing a detailed analysis of the semileptonic t (t) over bar -decay channel, we demonstrate that the production mode could lead to a similar to 5 sigma discovery at the high-luminosity LHC, while the effective hZ gamma coupling could be extracted with a similar to 15% accuracy. Extending the analysis to potential future pp colliders with 27 TeV and 100 TeV center-of-mass energies, we also show that the latter would allow precision measurements at the few percent level, rendering possible precise extractions of the spin and CP properties of the Higgs boson.
