flav-io/flavio v0.29

New physics in ε'/ε The highlight of this release is the addition of the observable ε'/ε, measuring the ratio of direct over indirect CP violation in K→ππ decays. This implementation is based on the results presented in arXiv:1807.02520 by J. Aebischer, C. Bobeth, A. Buras, J.-M. Gérard, and D. Straub. This is the first open source implementation of new physics contributions to this important observable taking into account all 114 ΔS=1 operators below the electroweak scale (or arbitrary SMEFT operators through wilson). Bugs fixed Sign error in new physics contributions to τ→Vl decays fixed Font issue when plotting on certain systems fixed (thanks to @peterstangl) Regression introduced in v0.28 affecting new physics contributions to meson mixing fixed Other improvements Various speed optimization
