Updated determinations of |V$_{us}$| with tau decays using new recent estimates of radiative corrections for light-meson leptonic decay rates
We update the determinations using the HFLAV 2018 report tau branching fraction results with recent new estimates of the \pi\ell2 <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mrow><mml:mi>π</mml:mi><mml:mi>ℓ</mml:mi><mml:mn>2</mml:mn></mml:mrow></mml:math> and K\ell2 <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mrow><mml:mi>K</mml:mi><mml:mi>ℓ</mml:mi><mml:mn>2</mml:mn></mml:mrow></mml:math> radiative corrections. There are minor changes of the central values and uncertainties.
