Description
I will introduce the Lagrangian formulation of microstructured test bodies containing all spin, dilation and shear charges and moving in a generalized non-Riemannian background. Using the equations of motion derived by this formulation I will study the evolution of the dynamical rest mass of the body. I will show that, due to the presence of non-metricity, the dynamical rest mass is no longer not a constant of motion, even with the imposition of additional constraints. This leads to novel Regge-like trajectories involving the dilation and shear (i.e. hadronic) charges of the particle.
