Nonleptonic decay dynamics
arXiv:2012.09483
Abstract
Using Chiral Perturbation Theory to properly account for the dynamics of nonleptonic decays, we found the Standard Model prediction for the CP violating ratio $\mbox{Re}\left(\varepsilon'/\varepsilon\right)=\left(14\pm 5\right) \times 10^{-4}$, where isospin breaking effects are included, in perfect agreement with the current experimental world average. Similar results have been reported by a recent release of improved lattice data.
