$D-\bar{D}$ mixing constraints on FCNC with a non-universal $Z^{\prime }$

Abstract

The BaBar and Belle collaborations have recently reported evidence for $D^0-{\bar{D}}^0$ mixing. This measurement provides the first significant constraint on FCNC in the up-quark sector for non-universal $Z^{\prime }$ models. Attributing the observed $D-\bar{D}$ mixing to new physics, we comment on the resulting rare $D$ and $t$ decays. We also show that a CP violating semileptonic asymmetry as large as $\sim 30$ is allowed by the experimental results.
