Search for an invisibly-decaying Higgs boson at LEP

A search for a Higgs boson produced in e<sup>+</sup>e<sup>−</sup> collisions in association with a Z boson and decaying into invisible particles is performed. Data collected at LEP with the L3 detector at centre-of-mass energies from 189 to 209 GeV are used, corresponding to...
