A resolution of the inclusive flavor-breaking τ |Vus| puzzle
We revisit the puzzle of |Vus| values obtained from the conventional implementation of hadronic-τ- decay-based flavor-breaking finite-energy sum rules lying >3σ below the expectations of three-family unitarity. Significant unphysical dependences of |Vus| on the choice of weight, w, and upper limi...
