Indirect<i>CP</i>violation in the neutral kaon system beyond leading logarithms
We have calculated the short distance QCD coefficient \eta_3 of the effective |\Delta S|=2-hamiltonian in the next-to-leading order. Since now all coefficients \eta_1, \eta_2 and \eta_3 are known beyond the leading log approximation, one can achieve a much higher precision in the theoretical analysis of \epsilon_K. The measured value for …
