超对称是自然界中一种新的对称性。贝尔编著的《弱尺度超对称》全面系统地介绍了粒子物理学中的超对称，首先阐述了超对称的基本概念，接着展示了如何将超对称纳入到描述基本粒子的理论框架中。书中采用了高能物理实验学家和唯象学家们所熟悉的四分量旋量表示，从而使得本书的可读性大为增强。本书迅速地将读者从抽象描述带入到构造基本粒子的超对称性规范理论，并最终给出对撞机和宇宙学实验观测量的计算。本书与高能实验和唯象理论结合得非常紧密，这是本书的一大特色。对于从事粒子物理实验和唯象研究的物理学家和研究生而言，这是一本全面、实用且易懂的教学参考书，并且包括大量的练习和补充材料，非常合适作为超对称理论的入门教材。阅读本书需要一些基本的标准模型和量子场论知识。
