Fermion dynamics in torsion theories

Understand

In this work we have studied the non-geodesical behaviour of particles with spin 1/2 in Poincar\'e gauge theories of gravity, via the WKB method and the Mathisson-Papapetrou equation.

• We have analysed the relation between the two approaches and we have argued the different advantages associated with the WKB approximation.
• Within this approach, we have calculated the trajectories in a particular Poincar\'e gauge theory, discussing the viability of measuring such a motion.
