Universality of the Poincaré gravitational form factor constraints
Abstract 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 constra...
