Revisit of the electromagnetic correction to $I ¨ \to I ¨ I ¨ I^½_{I ¨} $ and its implication for muon $g - 2$ based on $I ¨ $ data

Zhi-Xin Li, Ao Li, Jin Hao +2

In this work we focus on the evaluation of the leading-order hadronic vacuum polarization contribution from the $I ¨ I ¨ $ channel to the muon anomalous magnetic moment $a_{I^} ¼$ by using…

Unified study of two-meson and axion-meson production from semileptonic tau decays within resonance chiral framework

Jin Hao, Chun-Gui Duan, Zhi-Hui Guo

We carry out the joint study of the semileptonic tau decays into the two-meson and axion-meson channels, viz. $I ¨ ^{-} \to (P_{1} P_{2})^{-} I^½_{I ¨} $ and $I ¨ ^{-} \to I ¨ ^{-} (K^{-}) a I^½_{I ¨} $ within the fr…

Isospin-breaking contribution to the model-independent axion-photon-photon coupling in $U (3)$ chiral theory

Rui Gao, Jin Hao, Chun-Gui Duan +3

We pursue the calculation of the model-independent component of the axion-photon-photon coupling in the $U (3)$ chiral perturbation theory up to next-to-leading order, with the emph…
