CP asymmetry in B to $\phi$ K$_{s}$ decays in left-right models and its implications for B$_{s}$ decays
In left-right models the gluonic penguin contribution to b --> s s-bar s transition is enhanced by m_t/m_b due to the presence of (V+A) currents and by the larger values of loop functions than in the Standard Model. Together those may completely overcome the suppression due to small left-right mi...
