Higgs pseudo-observables in $e^+e^-\to h\gamma$
We analyse the process $e^+e^-\to h\gamma$ in the Standard Model (SM) and in generic extensions with heavy new physics, using the framework of Higgs pseudo-observables. We decompose the one-loop amplitude into separately gauge-invariant photon-pole, $Z$-pole, and non-pole contributions. For heavy new physics, we show t...
