Final results from DELPHI on the searches for SM and MSSM neutral Higgs bosons

These final results from DELPHI searches for the Standard Model(SM) Higgs boson, together with benchmark scans of the Minimal Supersymmetric Standard Model(MSSM) neutral Higgs bosons, used data taken at centre-of-mass energies between 200 and 209 GeV with a total integrated luminosity of 224 pb(-1). The data from 192 to 202 GeV are reanalysed with improved b-tagging for MSSM final states decaying to four b-quarks. The 95% confidence level lower mass bound on the Standard Model Higgs bosonis 114.1 GeV/c(2). Limits are also given on the lightest scalar and pseudo-scalar Higgs bosonsof the MSSM.
