Measurement of the Drell-Yan Cross Section in $p\bar{p}$ Collisions at the Tevatron

A preliminary measurement of the Drell-Yan cross section $\sigma(p\bar{p}\rightarrow\mu^+\mu^-)$ for dimuon masses in the range 30 - 200 GeV$/c^2$ is presented. The data were taken by the CDF Collaboration, and correspond to an integrated luminosity of $\approx$340 pb$^{-1}$ for $p\bar{p}$ collisions at an energy of 1.96~TeV$/c$. NLO calculations of this cross section are compared to the data.
