Search for the Rare Radiative Decay: $W\to \pi \gamma$ in \ppbar\ Collisions at $\sqrt{s}=1.96$ TeV

CDF collaboration, T. Aaltonen

We present a search for the rare radiative decay \wpigamma\ using data corresponding to an integrated luminosity of 4.3 \invfb\ of proton-antiproton collisions at a center of mass…
