超对称性研究回顾(英文)

Review of Supersymmetry

本文在讨论标准模型的成就与不足的基础上对近年来超对称性的研究进行了回顾 .如果在弱电标度下存在超对称性粒子 ,则它们应该在 LHC上得到证实 ,然而超对称性粒子质量的确定是非常困难的 .本文对 LHC各个点上如何从实验观察到的各种分布精确地确定超对称性粒子的质量及衰变分支比的方法进行了讨论 .

Under the discussion of the achievement and inadequacy of Standard Model we review the recent studies of supersymmetry. If supersymmetry exists at the electroweak scale, then it should be discovered at the LHC. Determining SUSY masses, however, is more difficult. In this paper, methods are dicussed to determine combinations of masses and of branching ratios precisely from experimentally observable distributions for the LHC Points.
