Abstract
We present a search for the rare radiative decay \wpigamma\ using data corresponding to an integrated luminosity of 4.3 fb<sup> -1</sup> of proton-antiproton collisions at a center of mass energy of 1.96 TeV collected by the CDF experiment at Fermilab. As no statistically significant signal is observed, we set a 95% confidence level upper limit on the relative branching fraction Γ(W<sup>±</sup>→ π<sup>±</sup>γ)/Γ(W<sup>±</sup>→e<sup>±</sup>v) at $6.4\times 10<sup>-5</sup>, a factor of 10 improvement over the prev
