摘要:

在本文中,我们重新评估的问题,推导的传播和识别的激发谱相关的(1+2)-D引力的vielbein和自旋连接的动力学扭转的存在下,而工作在一阶公式。一些特殊性指出,每当陈-西蒙斯长期被考虑到与双线性项的组合在扭转张量。我们提出了一个程序,以获得完整的传播,扩大自旋型运营商的代数的基础上,我们讨论在何种条件下的树级2点函数的极点对应的物理激励,不冲突的因果关系和幺正性。

英文摘要:

In this paper, we reassess the issue of deriving the propagators and identifying the spectrum of excitations associated to the vielbein and spin connection of (1+2)-D gravity in the presence of dynamical torsion, while working in the first-order formulation. A number of peculiarities is pointed out whenever the Chern-Simons term is taken into account along with a combination of bilinear terms in the torsion tensor. We present a procedure to derive the full set of propagators, based on an algebra of enlarged spin-type operators, and we discuss under which conditions the poles of the tree-level 2-point functions correspond to physical excitations that do not conflict with causality and unitarity.
