Studies of Z + photon production at CDF

We present studies of $Z \rightarrow l^{+} l^{-} + $ photon production with central photons where the Z decays into $e^{+}e^{-}$ or $\mu^{+}\mu^{-}$, using 4.5 fb$^{-1}$ of Tevatron $p \bar{p}$ collisions collected by the CDF detector at Fermilab. We measure the cross section for $Z \rightarrow l^{+} l^{-} + $ photon where the invariant mass of the two leptons is greater than 40 GeV and the photon, separated from both leptons, has transverse energy greater than 7 GeV. We then compare it to the next-to-leading-order calculation. We also present kinematic distributions of data events and compare them with the expected shapes from the standard model, with the specific goal of measuring potential beyond-the-standard-model anomalous triple gauge couplings between the $Z$ and the photon.
