We investigate the effect of unparticles in the pure b -> d penguin processes B-0 -> K-0(K) over bar (0) and B-+,B-0 -> phi pi(+,0). Since these processes receive dominant contributions due to the top quark in the loop, direct and mixing-induced CP asymmetry parameters in these processes are expected to be vanishingly small in the Standard Model. We find that due to the unparticle effect sizable nonzero CP violation could be possible in these channels. (C) 2008 Elsevier B.V. All rights reserved.
