高次导数系统中的规范对称性与W-代数

Gauge symmetry and W-algebra in higher derivative systems

Rabin Banerjee, Pradip Mukherjee, Biswajit Paul

摘要:

本文从哈密顿量的观点讨论了高导数拉格朗日系统的规范对称性问题。独立规范参数的数目一般是{\it{less}}比独立的初级第一类约束的数目,从而区别于传统的一阶系统。不同的模型被认为是说明性的例子。特别地,我们显示了刚性相对论粒子的规范对称性和W-代数之间的直接联系。

英文摘要:

The problem of gauge symmetry in higher derivative Lagrangian systems is discussed from a Hamiltonian point of view. The number of independent gauge parameters is shown to be in general {\it{less}} than the number of independent primary first class constraints, thereby distinguishing it from conventional first order systems. Different models have been considered as illustrative examples. In particular we show a direct connection between the gauge symmetry and the W-algebra for the rigid relativistic particle.
