WebWe review the status and future prospects of the determination of the CKM matrix element V_us using inclusive strange hadronic \tau{} decay data. We also review the results for V_us extracted from experimental measurements of some exclusive \tau{} decay channels such as \tau-> K \nu{} and \tau-> \pi \nu. WebTAU DECAY MODES Some of us still dream about discovering unexpected decay modes of the tau, decay modes that would lead to the discovery of new physics. Figure 1 shows two possibilities. In the upper diagram the τ-W vertex has unexpected behavior, another particle, x, is emitted. The W materializes into a standard pure leptonic final state.
