Universality of the Poincaré gravitational form factor constraints

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...
