Abstract
We analyze the unparticle effects on the lepton flavor universality violating ratios in [Formula: see text] transition, [Formula: see text]. We concentrate on the vector unparticles which contribute to the relevant Wilson coefficients [Formula: see text]. 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 [Formula: see text]. Constraints from [Formula: see text]–[Formula: see text] mixing, [Formula: see text], and the electron/muon anomalous magnetic moments are considered. It is found that the vector unparticles successfully explain [Formula: see text] with moderate values of model parameters.
