标题： Search for Charged Higgs bosons: Preliminary Combined Results Using LEP data Collected at Energies up to 209 GeV

摘要： 2000年，四个LEP实验在200至209 GeV之间的能量上收集了870 pb⁻¹的数据，其中约有510 pb⁻¹的能量高于206 GeV。 这些数据与之前在较低能量下收集的数据集进行了组合。 %以下为95%置信水平的界限。 对于标准模型两双峰扩展理论预测的带电希格斯玻色子，并且仅衰变到通道 H⁺→cs̄ 和 τ⁺ντ，得到的95%置信水平下的最低质量界限为78.6 GeV。 显示英文摘要

摘要： In the year 2000 the four LEP experiments have collected 870 pb-1 of data at energies between 200 and 209 GeV, with about 510 pb-1 above 206 GeV. These data have been combined with data sets collected earlier at lower energies. %The following 95% confidence level bounds have been obtained. For charged Higgs bosons predicted by two-doublet extensions of the Standard Model and decaying only into the channels H+->csbar and tau+nutau, a lower mass bound of 78.6 GeV is obtained, at the 95% confidence level.
