| 摘 要： | 本文在最一般的线性协变规范下计算了含有17个参数的有挠引力理论的传播子,发现拉氏函数中有三项对理论的粒子内容无影响。1-粒子是规范有关的非物理粒子,与原始拉氏量是否无鬼、无快子没有关系。

| Abstract: | Under a general linear covariant gauge condition, the propagators are calculated in a gravitational theory with torsion containing 17 parameters. It is showed that there are three terms in the Lagrangian having no contributions to the particle content of the theory. Jp=l- particle is a gauge-dependent non-physical particle, which does not effect whether the original Lagrangian is ghost-free and tachyon-free or not. |
