Predictions for $b \rightarrow ss\overline{d}$ and $b \rightarrow dd\overline{s}$ decays in the SM and with new physics

The b -> ssdbar and b -> ddsbar decays are highly suppressed in the SM, and are thus good probes of new physics (NP) effects. We discuss in detail the structure of the relevant SM effective Hamiltonian pointing out the presence of nonlocal contributions which can be about \lambda^{-4} (m_c^2/m...
