拉格朗日共形高自旋理论

Lagrangian conformal higher spin theory

Robert Marnelius

摘要:

在前一篇文章中,共形引力是通过共形空间中超锥上的精确作用原理导出的。在这里,它表明,同样的技术用于构建共形自旋2理论所代表的线性共形重力也可以用于建设共形的高自旋理论。在这些结构中的基本成分是规范不变的场强(曲率)。事实上,它们作为明显的共形场的存在本身就需要现在的共形理论。给出了超锥上自由理论作用量的一般形式。在时空中,这些行动被证明是表示在广义外尔张量的平方。共形自旋3和4是明确计算的。提出的理论是等效的自由理论的Fradkin和Linetsky。由于方程是2s阶的,所以很难实现一致的量化,但可能存在。预期会存在相互作用,这是这种方法背后的动机。

英文摘要:

In a previous paper conformal gravity was derived by means of a precise action principle on the hypercone in the conformal space. Here it is shown that the same technique used to construct conformal spin two theory as represented by linear conformal gravity may also be used for the construction of conformal higher spin theories. The basic ingredients in these constructions are gauge invariant field strengths (curvatures). In fact, their very existence as manifestly conformal fields requires the present conformal theory. The general form of the actions for the free theories on the hypercone are given. In spacetime these actions are shown to be expressed in terms of squares of generalized Weyl tensors. Conformal spin three and four are calculated explicitly. The theories are proposed to be equivalent to the free theories given by Fradkin and Linetsky. Since the equations are of order 2s a consistent quantization is difficult to achieve but might exist. Interactions are expected to exist and is the motivation behind this approach.
