Abstract
We update the |V$_{us}$| determinations using the HFLAV 2018 report tau branching fraction results with recent new estimates of the $\pi\ell2$ and $K\ell2$ radiative corrections. There are minor changes of the central values and uncertainties.
Author comments upon resubmission
List of changes
-
modified 2nd eq. in p.2 to indicate use of reduced Fermi constant and facilitate recognition of the units of each term
-
mentioned existence of additional recently published new radiative corrections, as requested
-
Table 1 & Figure 1 now report only Vus with tau measurements described in this document
-
Figure 1 now reports Vus with tau measurements for both discussed radiative corrections
-
captions of Table 1 and Figure 1 modified to account for content changes
