$ε^{'} / ε$ in and beyond the Standard Model

Jason Aebischer

Estimates of the CP violating observable $ε^{'} / ε$ have gained some attention in the past few years. Depending on the long-distance treatment used, they exhibit up…

QCD Improved Matching for Semi-Leptonic B Decays with Leptoquarks

Jason Aebischer, Andreas Crivellin, Christoph Greub

Leptoquarks (LQs) provide very promising solutions to the tensions between the experimental measurements and the SM predictions of $b \to s ℓ^{+} ℓ^{-}$ and $b \to c τ ν$ processes. In…

A Global Likelihood for Precision Constraints and Flavour Anomalies

Jason Aebischer, Jacky Kumar, Peter Stangl +1

We present a global likelihood function in the space of dimension-six Wilson coefficients in the Standard Model Effective Field Theory (SMEFT). The likelihood includes contribution…

Anatomy of $ε^{'} / ε$ beyond the Standard Model

Jason Aebischer, Christoph Bobeth, Andrzej J. Buras +1

We present for the first time a model-independent anatomy of the ratio $ε^{'} / ε$ in the context of the $Δ S = 1$ effective theory with operators invariant under QCD…

Master formula for $ε^{'} / ε$ beyond the Standard Model

Jason Aebischer, Christoph Bobeth, Andrzej J. Buras +2

We present for the first time a master formula for $ε^{'} / ε$ , the ratio probing direct CP violation in $K \to π π$ decays, valid in any theory beyond the Standard M…

BSM Hadronic Matrix Elements for $ε^{'} / ε$ and $K \to π π$ Decays in the Dual QCD Approach

Jason Aebischer, Andrzej J. Buras, Jean-Marc Gerard

We calculate for the first time all four-quark hadronic matrix elements of local operators possibly contributing to $K \to π π$ decays and in particular to the ratio $ε^{'} / ε$ beyond the…
