Recent D0 results on Z{gamma} production

PDF Version Also Available for Download.

Description

We report on a new search for anomalous {ital ZV}{sub {gamma}} ({ital V = Z}, {gamma}) couplings in the {ital Z}({ital ee}){gamma} mode with 89 pb{sup -1} of data. The following limits on anomalous coupling parameters were set at 95% CL: {vert_bar}{ital h{sup V}}{sub 10, 30}{vert_bar} {lt} 1.9, {vert_bar}{ital h{sup V}}{sub 20, 40}{vert_bar} {lt} 0.4. We also report on the first measurement of {ital Z(vv)}{gamma} production at hadron colliders using 14 pb{sup - 1} of data. Sensitivity to anomalous couplings in this channel is twice as good as that for the combined electron and muon channel analysis reported earlier. We ... continued below
