Search for the Standard Model Higgs boson at LEP in the year 2000

Searches for the Standard Model Higgs bosonhave been performed in the data collected by the DELPHIexperiment at LEP in the year 2000 at centre-of-mass energies between 200 and 209 GeV corresponding to a total integrated luminosity of 224 pb−1. No evidence for a Higgs signal is observed in the kinematically accessible mass range, and a 95% CL lower mass limit of 114.3 GeV/c2 is set, to be compared with an expected median limit of 113.5 GeV/c2 for these data.
