Measurement of the W boson mass at CDF

We describe a measurement of the $W$ boson mass using $\approx$ 2.2 fb$^{-1}$ of $\sqrt{s}$ = 1.96 TeV $p\bar{p}$ collision data collected by the CDF Run II detector at Fermilab. With 470,126 $W\rightarrow e\nu$ candidates and 624,708 $W\rightarrow\mu\nu$ candidates, we measure $m_W = 80387 \pm 19$ MeV/$c^{2}$. This is the most precise measurement of the $W$ boson mass to date.
