We consider the implication of the recent measurement of the W-boson mass $M_W$ [Science 376, 170 (2022)] for atomic parity violation experiments. We show that the change in $M_W$ shifts the Standard Model prediction for the ${}^{133}$Cs nuclear weak charge to $Q_W({}^{133}{\rm Cs})=-72.85(6)$, i.e. by $5.5\sigma$ from its current value. This brings existing experimental result for $Q_W({}^{133}{\rm Cs})$ into an essential agreement with the Standard Model. Using our revised value for $Q_W({}^{133}{\rm Cs})$, we readjust constraints on physics beyond the Standard Model.

Our approach should be contrasted with global fits with $M_W=80,433.5±9.4 MeV/c^2$ which do not show an appreciable change in the value of $sin^2θ̂_W$, but rather slight variations in a wide array of electroweak parameters [ref] .
