TeV-Scale字符串

TeV-Scale strings

David Berenstein

摘要:

本文讨论弦物理的现状,其中弦的张力是在TeV尺度左右。本文涵盖了微扰弦的模型构建基础,基于D-膜配置。这种弦结构的有效的低能物理描述进行了分析:如何实现异常取消,如何快速质子衰变是避免和D膜模型如何导致额外的$Z'$粒子。这篇评论还讨论了在TeV尺度上的弦的直接搜索范围,以及与味物理和轴子相关的模型构建的理论问题。

英文摘要:

This article discusses the status of string physics where the string tension is around the TeV scale. The article covers model building basics for perturbative strings, based on D-brane configurations. The effective low energy physics description of such string constructions is analyzed: how anomaly cancellation is implemented, how fast proton decay is avoided and how D-brane models lead to additional $Z'$ particles. This review also discusses direct search bounds for strings at the TeV scale, as well as theoretical issues with model building related to flavor physics and axions.
