Εk/εk at Next-to-leading in 1/nc and to Lowest Order Chpt
نویسنده
چکیده
Recent reviews and predictions for this quantity in the Standard Model and earlier references are in . Here, we report on a calculation 3 of this quantity in the chiral limit and next-to-leading (NLO) order in 1/Nc. We also discuss the changes when the known chiral corrections -final state interactions (FSI) and π0 − η mixingare included. Direct CP-violation in the K → ππ decay amplitudes is parameterized by εK εK = 1 √ 2 [ A [KL → (ππ)I=2] A [KL → (ππ)I=0] − A [KS → (ππ)I=2] A [KS → (ππ)I=0] ]

Chiral Limit Prediction for ε ′ K / ε K at NLO in 1 / N c 1
We report on a calculation of εK/εK at next-to-leading in the 1/Nc expansion and to lowest order in Chiral Perturbation Theory. We discuss the short-distance matching, the scale and scheme dependence as well as the long-distance short-distance matching. We include the two known chiral corrections to our result and discuss further order p4 corrections to it. September 2000 Work supported in part...
متن کاملNNLO contributions to εK and rare kaon decays
We discuss the theory prediction of εK and the rare K → πνν̄ decays and review the structure and current status of higher-order contributions to these flavour changing processes in the standard model in some detail. This includes the next-to-next-to-leading order QCD calculation to the charm quark contribution to K+ → π+νν̄ and to the charm-top quark contribution to εK . Electroweak corrections t...
متن کاملPhenomenology of Εk beyond Leading Logarithms
I present the QCD short distance coefficient η3 of the ∆S = 2 hamiltonian in the next-to-leading order (NLO) of renormalization group improved perturbation theory. Since now all QCD-factors η1, η2 and η3 are known with NLO accuracy, a much higher precision in the analysis of εK can be achieved. The CKM phase δ, |Vtd| and the mass difference ∆mBs in the B 0 s −B 0 s-system are predicted from the...
متن کاملM K and ε K in SUSY at the Next - to - Leading order
We perform a Next-to-Leading order analysis of ∆S = 2 processes beyond the Standard Model. Combining the recently computed NLO anomalous dimensions and the B parameters of the most general ∆S = 2 effective Hamiltonian, we give an analytic formula for ∆MK and εK in terms of the Wilson coefficients at the high energy scale. This expression can be used for any extension of the Standard Model with ...
متن کاملVariations around a problem of Mahler and Mendès France
We discuss the following general question and some of its extensions. Let (εk)k≥1 be a sequence taking its values in {0, 1}, which is not ultimately periodic. Define ξ := ∑ k≥1 εk/2 k and ξ′ := ∑ k≥1 εk/3 . Let P be a property valid for almost all real numbers. Is it true that at least one among ξ and ξ′ satisfies P ?
