标题： Searches at LEP

摘要： 对LEP2上的四个实验ALEPH、DELPHI、L3和OPAL进行了一系列广泛的新现象搜索。 每个实验在2000年为这些搜索提供了大约150 pb-1的e+e-湮灭数据，平均sqrt(s)为205.9 GeV（数据准备用于9月5日的LEPC会议）。 回顾了设置限制和评估数据中观察到的过量显著性的统计方法。 介绍了以下内容的搜索结果：标准模型希格斯玻色子、MSSM中的中性希格斯玻色子、带电希格斯玻色子、通过希格斯辐射产生的不可见衰变希格斯玻色子以及费米子非敏感希格斯玻色子。 简要总结了对超对称粒子（如gauginos、stops和staus）的搜索结果。 检查了光子反冲谱以寻找新物理的迹象。 显示英文摘要

摘要： Searches have been conducted for a broad range of new phenomena by the four experiments ALEPH, DELPHI, L3, and OPAL, at LEP2. Each experiment contributes approximately 150 pb-1 of e+e- annihilation data with a mean sqrt(s) of 205.9 GeV in 2000 to these searches (data prepared for the September 5 LEPC meeting). The statistical procedure for setting limits and evaluating the significance of excesses observed in the data is reviewed. Search results are presented for the Standard Model Higgs boson, the neutral Higgs bosons in the MSSM, charged Higgs bosons, invisibly decaying Higgs bosons produced by Higgs-strahlung, and fermiophobic Higgs bosons. Search results are briefly summarized for gauginos, stops, and staus. The photon recoil spectrum is checked for hints of new physics.
