Abstract
The space-like penguin contributions to branching ratios and CP asymmetries in charmless decays of to two pseudoscalar mesons are studied using the next-to-leading order low energy effective Hamiltonian. Both the gluonic penguin and the electroweak penguin diagrams are considered. We find that the effects are significant.
