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…

Beyond the standard model with sum rules
Damian Ejlli
The paper derives sum‑rule constraints on particle degrees of freedom and masses from requiring a finite, Lorentz‑invariant zero‑point stress‑energy tensor, and examines how these…
