-2018: A Christmas Story
Andrzej J. Buras
I was supposed to review the status of both at the CKM Workshop in September in Heidelberg and recently at the Discrete 2018 Conference in Vienna. Unfortunately I had…
The Dual QCD @ Work
Andrzej J. Buras
The Dual QCD (DQCD) framework, based on the ideas of 't Hooft and Witten, and developed by Bill Bardeen, Jean-Marc Gerard and myself in the 1980s is not QCD, a theory of quarks and…
Anatomy of 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 in the context of the effective theory with operators invariant under QCD…
Master formula for beyond the Standard Model
Jason Aebischer, Christoph Bobeth, Andrzej J. Buras +2
We present for the first time a master formula for , the ratio probing direct CP violation in decays, valid in any theory beyond the Standard M…
BSM Hadronic Matrix Elements for and 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 decays and in particular to the ratio beyond the…
The Return of Kaon Flavour Physics
Andrzej J. Buras
Kaon flavour physics has played in the 1960s and 1970s a very important role in the construction of the Standard Model (SM) and in the 1980s and 1990s in SM tests with the help of…
Dual QCD Insight into BSM Hadronic Matrix Elements for Mixing from Lattice QCD
Andrzej J. Buras, Jean-Marc Gerard
We calculate BSM hadronic matrix elements for mixing in the Dual QCD approach (DQCD). The ETM, SWME and RBC-UKQCD lattice collaborations find the matrix elements of…
Analytic inclusion of the scale dependence of the anomalous dimension matrix in Standard Model Effective Theory
Andrzej J. Buras, Martin Jung
The renormalization group equations (RGEs) in Standard Model effective theory are usually either solved analytically, neglecting the scale dependence of gauge and Yukawa couplings,…
and Matrix Elements of the Chromomagnetic Operators from Dual QCD
Andrzej Buras, Jean-Marc Gerard
We perform for the first time a direct calculation of on-shell hadronic matrix elements of chromomagnetic operators (CMO) in the Standard Model and beyond. To his end, we…
