一个BPS Skyrme模型

A BPS Skyrme model

C. Adam, J. Sanchez-Guillen, A. Wereszczynski

摘要:

在一组广义Skyrme模型中,我们确定了一个子模型,它既有无限多的对称性和Bogomolny界是饱和的无限多个精确孤子解。具体地说,子模型只包含重子流的平方和一个势项。此外,已经在经典水平上,该BPS Skyrme模型再现了原子核的液滴模型的某些特征。在这里,我们回顾模型的性质,我们讨论最简单的Skyrmion(核子)的半经典量子化。

英文摘要:

Within the set of generalized Skyrme models, we identify a submodel which has both infinitely many symmetries and a Bogomolny bound which is saturated by infinitely many exact soliton solutions. Concretely, the submodel consists of the square of the baryon current and a potential term only. Further, already on the classical level, this BPS Skyrme model reproduces some features of the liquid drop model of nuclei. Here, we review the properties of the model and we discuss the semiclassical quantization of the simplest Skyrmion (the nucleon).
