The energy-momentum tensor of the Standard Model with applications to energy conditions

The Standard Model of elementary particle physics is one of the most successful models of contemporary physics, its predictions being in full agreement with experiments. In this manuscript we consider the Lagrangian of the Standard Model as a geometric variational problem on a globally hyperbolic manifold and derive the associated energy-momentum tensor in a geometric invariant way. As an application, we investigate the validity of various energy conditions that arise in general relativity.
