The Complete Hamiltonian in the Next-To-Leading Order and its Phenomenological Implications
Stefan Herrlich
We briefly sketch the calculation of the effective low-energy -hamiltonian in the next-to-leading order of renormalization group improved perturbation theory. The result fo…
The Coefficient η_3 of the |ΔS|=2 Hamiltonian in the Next-To-Leading Order
Stefan Herrlich
I present the calculation of the QCD short distance coefficient of the -hamiltonian in the next-to-leading order (NLO) of renormalization group improved perturbation…
The Complete |Delta S|=2 Hamiltonian in the Next-To-Leading Order
Stefan Herrlich, Ulrich Nierste
We present the complete next-to-leading order short-distance QCD corrections to the effective \dstwo -hamiltonian in the Standard Model. The calculation of the coefficient is…
Indirect CP-Violation in the Neutral Kaon System Beyond Leading Logarithms and Related Topics
Ulrich Nierste
I describe in detail the calculation of the coefficients eta_3 and eta_1 of the low-energy Delta S=2 -hamiltonian describing K^0-K^0-bar-mixing in the next-to-leading order of reno…
Indirect CP-Violation in the Neutral Kaon System Beyond Leading Logarithms
Stefan Herrlich, Ulrich Nierste
We have calculated the short distance QCD coefficient η_3 of the effective |ΔS|=2-hamiltonian in the next-to-leading order. Since now all coefficients η_1, η_2 and η_3 are known be…
Evanescent Operators, Scheme Dependences and Double Insertions
Stefan Herrlich, Ulrich Nierste
The anomalous dimension matrix of dimensionally regularized four-quark operators is known to be affected by evanescent operators, which vanish in dimensions. Their definition…
