摘要：

本文介绍了最近的实验直接搜索希格斯玻色子和超越标准模型（BSM）物理在SUSY 07会议的全体会议上显示的概述。报告的结果对应的积分亮度高达2 fb-1的运行II数据从$p\bar{p}$碰撞收集的CDF和D 0实验在费米实验室Tevatron对撞机。涵盖的内容包括：标准模型（SM）希格斯玻色子（包括灵敏度投影）、标准模型的最小超对称扩展（MSSM）、带电希格斯玻色子和扩展希格斯模型、保持R宇称的超对称衰变、规范介导的超对称破缺模型、长寿命粒子、细夸克、额外规范玻色子、额外维度，以及最后基于签名的搜索。鉴于对撞机的出色性能和实验的持续生产力，Tevatron物理潜力在未来更大的数据集中看起来非常有希望发现。特别是，如果希格斯玻色子的质量很轻或接近160 GeV，就可以观察到它。

英文摘要：

This paper presents an overview of recent experimental direct searches for Higgs-boson and beyond-the-standard-model (BSM) physics shown in the plenary session at the SUSY07 conference. The results reported correspond to an integrated luminosity of up to 2 fb-1 of Run II data from $p\bar{p}$ collisions collected by the CDF and D0 experiments at the Fermilab Tevatron Collider. Searches covered include: the standard model (SM) Higgs boson (including sensitivity projections), the minimal supersymmetric extension of the standard model (MSSM), charged Higgs bosons and extended Higgs models, supersymmetric decays that conserve R-parity, gauge-mediated supersymmetric breaking models, long-lived particles, leptoquarks, extra gauge bosons, extra dimensions, and finally signature-based searches. Given the excellent performance of the collider and the continued productivity of the experiments, the Tevatron physics potential looks very promising for discovery in the coming larger data sets. In particular, the Higgs boson could be observed if its mass is light or near 160 GeV.
