B. Abbott et al., Z-GAMMA PRODUCTION IN P(P)OVER-BAR COLLISIONS AT ROOT-S=1.8 TEV AND LIMITS ON ANOMALOUS ZZ-GAMMA AND Z-GAMMA-GAMMA COUPLINGS, Physical review. D. Particles and fields, 57(7), 1998, pp. 3817-3821
We present a study of Z gamma+X production in <p(p)over bar> collision
s at root s=1.8 TeV from 97 (87) pb(-1) of data collected in the ee ga
mma (mu mu gamma) decay channel with the D0 detector at Fermilab. The
event yield and kinematic characteristics are consistent with the stan
dard model predictions. We obtain limits on anomalous ZZ gamma and Z g
amma gamma couplings for form factor scales Lambda=500 GeV and Lambda=
750 GeV. Combining this analysis with our previous results yields 95%
C.L. limits \h(30)(Z)\<0.36, \h(40)(Z)\<0.05, \h(30)(gamma)\<0.37, and
\h(40)(gamma)\<0.05 for a form factor scale Lambda = 750 GeV. [S0556-
