这些来自德尔菲搜索标准模型SM希格斯玻色子的最终结果,以及最小超对称标准模型MSSM中性希格斯玻色子的基准扫描,使用了质心能量在200 - 209 GeV之间的数据,总积分光度为224 pB-1。用改进的b标记重新分析了192 - 202 GeV的数据,MSSM末态衰变到4个B-1。夸克标准模型希格斯玻色子的95%置信水平下限质量为114.1 GeV。质量限制也给出了最轻的标量和赝标量希格斯玻色子的MSSM。
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 reanalyzed 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 boson is 114.1 GeV. Mass limits are also given on the lightest scalar and pseudo-scalar Higgs bosons of the MSSM.
