英文摘要	The process e(+)e(-) --> Z gamma gamma - gamma> is studied in 0.5 fb(-1) of data collected with the L3 detector at centre-of-mass energies between 130.1 GeV and 201.7 GeV. Cross sections are measured and found to be consistent with the Standard Model expectations. The study of the least energetic photon constrains the quartic gauge boson couplings to -0.008 GeV-2 < a(0)/Lambda (2) < 0.005 GeV-2 and -0.007 GeV-2 < a(c)/Lambda (2) < 0.011 GeV-2, at 95% confidence level.
