Abstract

The importance of dipole penguin operator, O₁₁ = (g_s/8π²)m_b s σ_μνRT^a b G^μν_a, on B decays is demonstrated. It is shown that branching ratios for the inclusive decay b→ s s s, the semi-inclusive decay b→ sϕ, and the exclusive decay B→ πK are enhanced by 20% to 30%. A useful consequence of this calculation is the inclusive b→ ss s spectrum which will be essential in isolating pure penguin process.
