Within this approach, we calculate the trajectories in a particular Poincare gauge theory, discussing the viability of measuring such a motion.engjournal articlehttp://dx.doi.org/10.1088/1475-7516/2019/04/039https://iopscience.iop.org/open access53General-relativityEquationsGravitySpin.Física (Física)22 Física
