Study of $W\gamma$ Production at the Tevatron

We report a measurement of $p\bar{p}$ $\to l^+ \nu$ $\gamma$ + X at $\sqrt{s}$ = 1.96 TeV produced at the Fermilab Tevatron using 1.2 $fb^{-1}$ of data collected by the CDF II detector. This channel has contributions from $W$ bosons produced with initial and final state photon radiation and from photons emitted due to the direct $WW\gamma$ coupling. Events are selected with electrons (muons) with $E_T$ $>$ 20 GeV ($p_T$ $>$ 20 GeV/c), and isolated photons with $E_T$ $>$ 15 GeV and $|$$\eta$$|$$<$2.8. The measured cross sections and kinematic distributions are compared to Standard Model electroweak predictions.
