Constraining unparticle physics from $CP$ violation in Cabibbo-favored decays of D mesons

Abstract

According to the standard model, the Cabibbo-favored (CF) decays are $CP$ conserve at tree level. Observation of any finite $CP$ asymmetry can be received as a signal of new physics. In CF charm meson decays, $D^0\to K^{-}{\pi }^{+}$ and $D^{+}\to K_s^0{\pi }^{+}$, the following experimental values for their $CP$ asymmetry are reported, respectively: ($0.3\pm 0.7$) % and ($-0.41\pm 0.09$) %. The value of the later can be attributed to the mixing of $K^0$ and $\overline{K^0}$, however, its contribution is about ($-0.332\pm 0.006$) %. In this paper, we use these experimental results to constrain the unparticle stuff as a new physics which may contribute to these $CP$ asymmetries.
