Search for the Standard Model Higgs boson with the OPAL detector at LEP

The OPAL Collaboration

(Received: 13 March 2002 / Revised version: 9 October 2002 / Published online: 13 December 2002 )

This paper summarises the search for the Standard Model Higgs boson in e+ e- collisions at centre-of-mass energies up to 209 GeV performed by the OPAL Collaboration at LEP. The consistency of the data with the background hypothesis and various Higgs boson mass hypotheses is examined. No indication of a signal is found in the data and a lower bound of 112.7  GeV/c2 is obtained on the mass of the Standard Model Higgs boson at the 95% CL.
