Calculation of epsilon'/epsilon
Stefano Bertolini
I shortly review the present status of the theoretical calculations of epsilon'/epsilon and the comparison with the present experimental results. I discuss the role of higher order…
The Delta I = 1/2 Rule and B_K at O(p^4) in the Chiral Expansion
S. Bertolini, J. O. Eeg, M. Fabbrichesi +1
We calculate the hadronic matrix elements to in the chiral expansion for the () decays and the () - oscillation. This is done wit…
The Physics of Mixing: and in the Chiral Quark Model
V. Antonelli, S. Bertolini, M. Fabbrichesi +1
We compute the parameter and the mass difference of the system by means of the chiral quark model. The chiral coefficients of the relevant $…
A New Estimate of
S. Bertolini
We discuss a new estimate of in the kaon system. The present approach is based on the evaluation of the hadronic matrix elements of the \mbox{} e…
A New Estimate of
S. Bertolini, J. O. Eeg, M. Fabbrichesi
We discuss direct violation in the standard model by giving a new estimate of in kaon decays. Our analysis is based on the evaluation of the hadroni…
The Selection Rule
V. Antonelli, S. Bertolini, M. Fabbrichesi +1
We compute the isospin and 2 amplitudes for the decay of a kaon into two pions by estimating the relevant hadronic matrix elements in the chiral quark model. The results are…
