Abstract

A search for the neutral Higgs boson in the processes e+e→ Z → H0γ → qq̅ and e+e → Z → Z∗H0 → qq̅γγ has been performed using 2.8 million hadronic Z decays collected with the L3 detector at LEP from 1991 through 1994. No evidence for these processes has been observed. Upper limits at 95% confidence level for the corresponding cross sections have been set and the results have been compared with theoretical predictions beyond the Standard Model.
