Probing the CP Property of ALP-photon Interactions at Future Lepton Colliders

Jian-Nan Ding, Yandong Liu, Muyuan Song

We investigate a charge-parity (CP) odd axion-like particle (ALP) featuring simultaneous CP-conserving ($a{F}_{\hat{I}¼\hat{I}½}{\tilde{F}}^{\hat{I}¼\hat{I}½}$) and CP-violating ($a{F}_{\hat{I}¼\hat{I}½}{F}^{\hat{I}¼\hat{I}½}$) ALP-ph…
