关于高自旋场的量子化

On the Quantization of the Higher Spin Fields

J. W. Wagenaar, T. A. Rijken

摘要:

本文用Dirac约束Hamilton方法研究了有质量高自旋($1\leq j\leq2$)场在完全自由和与辅助场耦合两种情况下的量子力学性质。通过确定和讨论所有约束和拉格朗日乘子,并给出所有等时(反)对易关系,给出了一个完整的约束分析和量化。我们还构造了相应的传播子。在自由的情况下,我们得到了著名的传播,并表明他们是不协变的,这也是众所周知的。在耦合的情况下,我们得到的协变传播(在自旋3/2的情况下,这需要$b=0$),并表明,他们有一个光滑的无质量的限制连接完美的无质量的情况下(辅助领域)。我们注意到,在自旋为3/2和自旋为2的情况下,耦合到守恒流的大质量传播子只有一个光滑的限制,纯无质量的自旋传播子,当有鬼的情况下,有质量的情况。

英文摘要:

In this article we quantize (massive) higher spin ($1\leq j\leq2$) fields by means of Dirac's Constrained Hamilton procedure both in the situation were they are totally free and were they are coupled to (an) auxiliary field(s). A full constraint analysis and quantization is presented by determining and discussing all constraints and Lagrange multipliers and by giving all equal times (anti) commutation relations. Also we construct the relevant propagators. In the free case we obtain the well-known propagators and show that they are not covariant, which is also well known. In the coupled case we do obtain covariant propagators (in the spin-3/2 case this requires $b=0$) and show that they have a smooth massless limit connecting perfectly to the massless case (with auxiliary fields). We notice that in our system of the spin-3/2 and spin-2 case the massive propagators coupled to conserved currents only have a smooth limit to the pure massless spin-propagator, when there are ghosts in the massive case.
