A novel route to V us

Already in the past, hadronic τ decays have served as an interesting source to obtain inform ati n on the parameters of the Standard Model, like the strong couplingαs or the strange quark mass. Below it will be shown that the appr oach to obtain the strange mass from the hadronicτ-decay width can be turned into a determination of the CKM mat rix elementVus… (More)
