چکیده
This talk contains a short overview of the history of the interplay of the weak and the strong interaction and CP -violation. It describes the phenomenology and the basic physics mechanisms involved in the Standard Model calculations of K → ππ decays with an emphasis on the evaluation of Penguin operator matrix-elements. a Presented at the Symposium and Workshop ”Continuous Advances in QCD 2002/Arkadyfest,” Minneapolis, USA, 17-23 May 2002, to be published in the

Electroweak Penguins and Two - Body B Decays
We discuss the role of electroweak penguins in B decays to two light pseudoscalar mesons. We confirm that the extraction of the weak phase α through the isospin analysis involving B → ππ decays is largely unaffected by such operators. However, the methods proposed to obtain weak and strong phases by relating B → ππ, B → πK and B → KK decays through flavor SU(3) will be invalidated if electrowea...
متن کاملCharming Penguins Strike Back
By using the recent experimental measurements of B → ππ and B → Kπ branching ratios, we find that factorization is unable to reproduce the observed BRs even taking into account the uncertainties of the input parameters. Charming and GIM penguins allow to reconcile the theoretical predictions with the data. Because of these large effects, we conclude, however, that it is not possible, with the p...
متن کاملPenguins in B Decays
We report on recent progress in studying two aspects of B physics, in which penguin amplitudes play an important role: 1. Bounds on penguin pollution in B(t) → ππ constraining CKM parameters, and a lower bound on B → ππ improving precision in sin 2α. 2. A suggestion for measuring the photon polarization in electroweak penguin decay, B → K1(1400)γ, providing a precision test of the Standard Model.
متن کاملCP Violation and the Role of Electroweak Penguins in Non-leptonic B Decays
The phenomenon of CP violation in the B system and strategies for extracting CKM phases are reviewed. We focus both on general aspects and on some recent developments including CP-violating asymmetries in Bd decays, the Bs system in light of a possible width difference ∆Γs, charged B decays, and SU(3) relations among certain transition amplitudes. In order to describe the relevant non-leptonic ...

We report on dispersive and finite energy sum rule analyses of the electroweak penguin matrix elements (ππ)2|Q7,8|K 0 in the chiral limit. We accomplish the correct perturbative matching (scale and scheme dependence) at NLO in αs, and we describe two different strategies for numerical evaluation.
