Theory of Nonleptonic B Decays
Luca Silvestrini
I briefly review some recent progress in the theory of nonleptonic B decays. After introducing the operator product expansion and the relevant effective Hamiltonian, I discuss the…

Constraints on an enhanced sbar d Z vertex from epsilon'/epsilon
Luca Silvestrini
We analyze rare kaon decays in models in which the dominant new effect is an enhanced sbar d Z vertex Z_{ds}. We point out that in spite of large theoretical uncertainties the CP-v…
