Abstract
The recent CDF mass measurement of 80,433 9 MeV is the most precise direct measurement. However, this result deviates from the Standard Model predicted mass of 80,359.1 5.2 MeV by . The CDF experiment used an older version of the ResBos code that was only accurate at NNLL+NLO, while the ResBos2 code is able to make predictions at NLL+NNLO accuracy. We determine that the data-driven techniques used by CDF capture most of the higher order corrections, and using higher order corrections would result in a decrease in the value reported by CDF by at most 10 MeV.
