庞加莱引力形状因子约束的普适性

Universality of the Poincaré gravitational form factor constraints

Cédric Lorcé, Peter Lowdon

摘要:

相对论自旋态是依赖于约定的。在这项工作中,我们证明了零动量转移限制的领导两个形状因子的能量动量张量矩阵元素的分解是独立的这种选择。特别是,我们证明了这些约束条件是不敏感的相应的状态是否是大规模的或没有,他们纯粹是由于庞加莱协方差的状态。

英文摘要:

Relativistic spin states are convention dependent. In this work we prove that the zero momentum-transfer limits of the leading two form factors in the decomposition of the energy-momentum tensor matrix elements are independent of this choice. In particular, we demonstrate that these constraints are insensitive to whether the corresponding states are massive or not, and that they arise purely due to the Poincaré covariance of the states.
