| dc.description | We study the penguin pollution in the B^0 -> J/psi K_S decay up to leading power in 1/m_b and to next-to-leading order in α_s, m_b being the b quark mass and α_s the strong coupling constant. The deviation ΔS_{J/psi K_S} of the mixing-induced CP asymmetry from sin(2ϕ_1) and the direct CP asymmetry A_{J/psi K_S} are both found to be of O(10^{-3}) in a formalism that combines the QCD-improved factorization and perturbative QCD approaches. | |
