QCD axions and domain walls in dense matter under compact stellar conditions
Zhen-Yan Lu, Shu-Peng Wang, Qi Lu +2
In compact stellar environments, the stability of dense QCD matter requires the simultaneous fulfillment of charge neutrality and beta equilibrium. In this work, we study how tempe…

New contribution to the anomalous decay in SU(2) chiral perturbation theory
Zhen-Yan Lu, Shu-Peng Wang, Qi Lu
The introduction of axions gives rise to additional one-loop diagrams for the two-photon decays of neutral pions via axion-pion mixing. We compute this correction that has been ove…

New axion contribution to the two-photon decays of neutral pions
Zhen-Yan Lu, Yang Huang, Ji-Gui Cheng +2
The presence of axions introduces new diagrams at one-loop order to the two-photon decays of the neutral pion through axion-pion mixing. In this work, we calculate this correction,…
