On the importance of NNLO QCD and isospin-breaking corrections in $$\varepsilon '/\varepsilon $$ ε′/ε
Abstract Following the 1999 analysis of Gambino, Haisch and one of us, we stress that all the recent NLO analyses of $$\varepsilon '/\varepsilon $$ ε′/ε in the Standard Model (SM) suffer from the renormalization scheme dependence present in the electroweak penguin contributions as well as from...
