collisions collected by the OPAL detector at LEP. The search was made
for events of the types e+e- --> (e+e-, mu+mu- or nunu-)H0, H0-->qqBAR
and was based on approximately 78 pb-1 of data taken at center-of-mas
s energies between 88 and 95 GeV in the years 1990-1993. The present s
tudy, combined with previous OPAL publications, excludes the existence
of a Minimal Standard Model Higgs boson with mass below 56.9 GeV at t
he 95% confidence level.
