Abstract

The LHCb Collaboration has recently measured the difference of time-integrated $C P$ asymmetry in $D^{0} \to K^{+} K^{-}$ and $D^{0} \to π^{+} π^{-}$ decays, more precisely. The reported value is $Δ A_{C P} = - 0.10 \pm 0.08 (stat) \pm 0.03 (syst) %$ which indicates no evidence for $C P$ violation. We consider the possible unparticle physics contribution in this quantity and by using the LCHb data try to constrain the parameter space of unparticle stuff.
