N2 - (Formula presented) flavor tagging will be extensively studied at the asymmetric (Formula presented) factories due to its importance in (Formula presented) asymmetry measurements. The primary tagging modes are the semileptonic decays of the (Formula presented) (lepton tag), or the hadronic (Formula presented) decays (kaon tag). We suggest that looking for time dependent (Formula presented) asymmetries in events where one (Formula presented) is tagged leptonically and the other one is tagged with a kaon could result in an early detection of (Formula presented) violation. Although in the standard model these asymmetries are expected to be small, (Formula presented) they could be measured with about the same amount of data as in the “gold-plated” decay (Formula presented) In the presence of physics beyond the standard model, these asymmetries could be as large as (Formula presented) and the first (Formula presented) violation signal in the (Formula presented) system may show up in these events. We give explicit examples of new physics scenarios where this occurs.
