Abstract
The double-radiative process e(+)e(-) → Zγγ → q $(q) over bar $ γγ where the two hard photons escape detection at low polar angles into opposite directions, is studied in 0.62 fb(-1) of data collected with the L3 detector at LEP at centre-of-mass energies between 188.6 and 209.2 GeV. The cross sections are measured and found to be consistent with the Standard Model expectations. © 2005 Published by Elsevier B.V.
