We study the $h \gamma Z$ coupling, which is a loop induced coupling in the Standard Model (SM), to probe new physics. In a global fit based on the SM Effective Field Theory, measurement of the SM $h \gamma Z$ coupling can provide a very useful constraint, in particular for the precise determination of $hZZ$ and $hWW$ couplings. At the International Linear Collider (ILC), there are two direct ways to study the $h \gamma Z$ coupling: one is to measure the branching ratio of the $h \to \gamma Z…

ILC Study Questions for Snowmass 2021
To aid contributions to the Snowmass 2021 US Community Study on physics at the International Linear Collider and other proposed $e^+e^-$ colliders, we present a list of study questions that could be
Muon $g-2$ at multi-TeV muon collider
The long-standing discrepancy of muon $g-2$ is a hint of new physics beyond the standard model of particle theory. In this letter we show that heavy new physics contribution may be fully tested in a

Diphoton resonances at the ILC
In this paper, we study the direct production of the diphoton resonance $X$, which was suggested by 2015 data at the LHC, in
Single Higgs production in association with a photon at electron-positron colliders in extended Higgs models
We study associated Higgs production with a photon at electron-positron colliders, $e^+e^-\to h\gamma$, in various extended Higgs models, such as the inert doublet model (IDM), the inert triplet
