Anatomy of $\varepsilon'/\varepsilon$ beyond the Standard Model
Jason Aebischer, Christoph Bobeth, Andrzej J. Buras +1
The paper provides a model‑independent analysis of the CP‑violating ratio ε′/ε in kaon decays using ΔS=1 effective theory and the Standard Model Effective Field Theory, deriving a…

Master formula for $\varepsilon'/\varepsilon$ beyond the Standard Model
Jason Aebischer, Christoph Bobeth, Andrzej J. Buras +2
The authors derive a master formula for the direct CP‑violation ratio ε'/ε in K→ππ decays that is applicable to any beyond‑Standard‑Model scenario, using recent hadronic matrix ele…
