- Title
R(K(∗)) with vector unparticles.

- Abstract
We analyze the unparticle effects on the lepton flavor universality violating ratios in b → s transition, R (K (∗)). We concentrate on the vector unparticles which contribute to the relevant Wilson coefficients C 9 , 1 0 . New effects appear in the form of some powers of the momentum transfer squared, which is a different feature from other new physics (NP) models like leptoquarks or Z ′ . Constraints from B s – B ̄ s mixing, B s → μ + μ − , and the electron/muon anomalous magnetic moments are considered. It is found that the vector unparticles successfully explain R (K (∗)) with moderate values of model parameters.
