Title: Study of Z{gamma} Events and Limits on Anomalous ZZ{gamma} and Z{gamma}{gamma} Couplings in pp Collisions at {radical}(s)=1.96 TeV

Abstract

We present a measurement of the Z{gamma} production cross section and limits on anomalous ZZ{gamma} and Z{gamma}{gamma} couplings for form-factor scales of {lambda}=750 and 1000 GeV. The measurement is based on 138 (152) candidates in the ee{gamma} ({mu}{mu}{gamma}) final state using 320(290) pb{sup -1} of pp collisions at {radical}(s)=1.96 TeV. The 95% C.L. limits on real and imaginary parts of individual anomalous couplings are vertical bar h{sub 10,30}{sup Z} vertical bar <0.23, vertical bar h{sub 20,40}{sup Z} vertical bar <0.020, vertical bar h{sub 10,30}{sup {gamma}} vertical bar <0.23, and vertical bar h{sub 20,40}{sup {gamma}} vertical bar <0.019 for {lambda}=1000 GeV.
