含磁项的Rarita-Schwinger场零无穷远渐近对称性

Asymptotic symmetries at null-infinity for the Rarita-Schwinger field with magnetic term

Bilyana L. Tomova

摘要:

本文研究了四维渐近平坦时空中自由无质量Rarita-Schwinger场的磁荷。这是将双BMS电荷的研究扩展到超重力的第一步。磁荷的出现是由于在作用量中加入了边界项。这一项类似于杨-米尔斯理论中的θ项。在零无穷大的无穷维代数发现,无论是对电力和磁荷。

英文摘要:

In this paper we study the magnetic charges of the free massless Rarita-Schwinger field in four dimensional asymptotically flat space-time. This is the first step towards extending the study of the dual BMS charges to supergravity. The magnetic charges appear due to the addition of a boundary term in the action. This term is similar to the theta term in Yang-Mills theory. At null-infinity an infinite dimensional algebra is discovered, both for the electric and magnetic charge.
