Isospin-breaking in $$\varepsilon '/\varepsilon $$ ε′/ε : impact of $$\eta _0$$ η0 at the dawn of the 2020s
Abstract For direct CP-violation in $$K\rightarrow \pi \pi $$ K→ππ decays, the usual isospin-breaking effects at the percent level are amplified by the dynamics behind the $$\Delta I=1/2$$ ΔI=1/2 rule and conventionally encoded in $$\Omega _\mathrm{IB}$$ ΩIB parameters. The updated prediction $$\Ome...
