Study Z gamma events and limits on anomalous ZZ gamma and Z gamma gamma couplings in pp(-) collisions at root s=1.96 Tev

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(-1) of p (p) over bar collisions at root s=1.96 TeV. The 95% C.L. limits on real and imaginary parts of individual anomalous couplings are vertical barh(10,30)(Z) vertical bar< 0.23, vertical barh(20,40)(Z) vertical bar< 0.020, vertical barh(10,30)(gamma) vertical bar< 0.23, and vertical barh(20,40)(gamma) vertical bar< 0.019 for Lambda=1000 GeV.
