Measurement of $Z \gamma$ Production at CDF

We present results from studies of photons produced in association with $Z$ bosons in $p\overline{p}$ collisions at $\sqrt{s} =$ 1.96 TeV at the Tevatron. Tri-linear gauge couplings are fundamental predictions of the Standard Model, and studying these couplings provides a sensitive test for non-Standard Model interactions. Here we compare measurements using 2~$fb^{-1}$ of CDF data with Standard Model predictions and predictions from models containing anomalous couplings.
