Hunting for Direct CP Violation in Adv. High Energy Phys. (IF 1.7) Pub Date : 2022-02-23 Sheng-Tao Li, Gang Lü
In perturbative QCD approach, based on the first order of isospin symmetry breaking, we study the direct violation in the decay of . An interesting mechanism is applied to enlarge the violating asymmetry involving the charge symmetry breaking between and . We find that the violation is large by the mixing mechanism when the invariant masses of the pairs are in the vicinity of the resonance. For the

Calculated Event Rates for Axion Detection via Atomic and Nuclear Processes Adv. High Energy Phys. (IF 1.7) Pub Date : 2022-02-22 John D. Vergados, Paraskevi C. Divari, Hiroyasu Ejiri
The possibility of detection of 5.5 MeV and 14.4 keV solar axions by observing axion-induced nuclear and atomic transitions is investigated. The presence of nuclear transitions between spin orbit partners can be manifested by the subsequent deexcitation via gamma ray emissions. The transition rates can also be studied in the context of radiative axion absorption by a nucleus. The elementary interaction
