弱尺度超对称：从超场到散射事例 下载 pdf 百度网盘 epub 免费 2025 电子书 mobi 在线

　　超对称是自然界中一种新的对称性。本书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。

读者对象：粒子物理、理论物理和场论等专业的高年级本科生、研究生和相关专业的科研人员。

书籍介绍

《弱尺度超对称:从超场到散射事例》是一本英文书。Supersymmetric models of particle physics predict new superpartner matter states for each particle in the Standard Model． These superpartners will have wide ranging implications， from cosmology to observations at high energy accelerators， such as CERN's LHC． In this 2006 text， the authors develop the basic concepts of supersymmetry and show how it can be incorporated into a theoretical framework for describing unified theories of elementary particles． They develop the technical tools of supersymmetry using four—component spinor notation familiar to high energy experimentalists and phenomenologists． The text takes the reader from an abstract formalism to a straightforward recipe for writing supersymmetric gauge theories of particle physics， and ultimately to the calculations necessary for practical applications at colliders and in cosmology． This is a comprehensive， practical and accessible introduction to supersymmetry for experimental and phenomenological particle physicists and graduate students． Exercises and worked examples that clarify the material are interspersed throughout．
