The production rate and kinematics of photons produced in association with Z bosons are studied using 2 fb−1 of p{bar p} collision data collected at the Collider Detector at Fermilab. The cross section for p{bar p} → ll−? + X (where the leptons l are either muons or electrons with dilepton mass M{sub l{ell}}> 40 GeV/c2, and where the photon has transverse energy E{sub T}{sup?}> 7 GeV and is well separated from the leptons) is 4.6 ± 0.2 (stat) ± 0.3 (syst) ± 0.3 (lum) pb, which is consistent with standard model expectations. We use the photon ET distribution from Z{gamma} events where the Z has decayed to?+?−, e+e−, or?{bar {nu}} to set limits on anomalous (non-standard-model) trilinear couplings between photons and Z bosons.
