We update the sm predictions and parametric uncertainties in EWPOs using a new input value of mw = 80.3692 GeV, using the code of https://inspirehep.net/files/2825974ed6cc7c9d62dde94d21263942.
The code computes Delta alpha(mW) = 1-alpha(0)/alpha(mW) = 0.058316373237 in the OS scheme.
Our updated value of alphaEW(mz)_MSbar is obtained by translating the SM prediction from Hannes code, delta alpha = 0.058316373237, from the OS to MSbar scheme by doing the shift in delta alpha (eq 10.21 in PDG review)
alpha0/(1 - 0.058316373237 - 0.007122)
