Measurement of Z gamma production in pp[over-bar] collisions at [sqrt]s=1.96 TeV
The production rate and kinematics of photons produced in association with Z bosons are studied using 2 fb-1 of pp[over-bar] collision data collected at the Collider Detector at Fermilab. The cross section for pp[over-bar] -->ℓ+ℓ-γ+X (where the leptons ℓ are either muons or electrons with dilept...

| description | The production rate and kinematics of photons produced in association with Z bosons are studied using 2 fb-1 of pp[over-bar] collision data collected at the Collider Detector at Fermilab. The cross section for pp[over-bar] -->ℓ+ℓ-γ+X (where the leptons ℓ are either muons or electrons with dilepton mass Mℓℓ>40 GeV/c[superscript 2], and where the photon has transverse energy ETγ>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 Zγ events where the Z has decayed to mu+mu-, e+e-, or nu nu[over-bar]to set limits on anomalous (non standard model) trilinear couplings between photons and Z bosons. |
