Measurements of Charged Current Lepton Universality and |V[subscript us]| Using Tau Lepton Decays to e-ν[over-bar]eνtau, mu-ν[over-bar]muν, pi-νtau, and K-νtau

Measurements of Charged Current Lepton Universality and |V[subscript us]| Using Tau Lepton Decays to e-ν[over-bar]eνtau, mu-ν[over-bar]muν, pi-νtau, and K-νtau

Using 467  fb-1 of e+e- annihilation data collected with the BABAR detector, we measure B(τ- -->mu-ν̅ muντ)/B(τ- -->e-ν̅ eντ)=(0.9796±0.0016±0.0036), B(τ- -->pi-ντ)/B(τ- -->e-ν̅ eντ)=(0.5945±0.0014±0.0061), and B(τ-→K-ντ)/B(τ- -->e-ν̅ eντ)=(0.03882±0.00032±0.00057), where the uncertai...
