M. Acciarri et al., Search for anomalous ZZ gamma and Z gamma gamma couplings in the process e(+)e(-)-> Z gamma at LEP, PHYS LETT B, 489(1-2), 2000, pp. 55-64
We search for anomalous trilinear gauge couplings in the ZZ gamma and Z gam
ma gamma vertices using data collected with the L3 detector at LEP at a cen
tre-of-mass energy root s = 189 GeV. Na evidence is found and limits on the
se couplings and on new physics scales are derived from the analysis of the
process e(+)e(-) -> Z gamma. (C) 2000 Elsevier Science B.V. All rights res
