Probing New Physics at future electron positron Higgs factories via e^+e^-→ Zγ process

Direct searches and precision measurements are the two main complementary methods for identifying New Physics at colliders.The next generation of e^+e^-Higgs factories,including CEPC,FCC-ee,ILC and CLIC,is designed to deliver millions of clean Higgs events,together with large samples of other physics processes.
