螺旋度和连续自旋费米子场的统一表述

Unified formulation for helicity and continuous spin fermionic fields

K. B. Alkalaev, Alexander Chekmenev, Maxim Grigoriev

摘要:

提出了$d$维Minkowski空间中任意混合对称型一般无质量费米子场的统一BRST表述。根据实参数的值,系统描述螺旋度场或连续自旋场。从统一表述出发,导出了三重态表述、Fang-Fronsdal-Labastida表述、光锥表述等等价表述,并讨论了展开表述。

英文摘要:

We propose a unified BRST formulation of general massless fermionic fields of arbitrary mixed-symmetry type in $d$-dimensional Minkowski space. Depending on the value of the real parameter the system describes either helicity fields or continuous spin fields. Starting with the unified formulation we derive a number of equivalent descriptions including the triplet formulation, Fang-Fronsdal-Labastida formulation, light-cone formulation and discuss the unfolded formulation.
