Show affiliationsWe derive a formula which allows the computation of the energy - momentum tensor in an arbitrarily curved spacetime from a Lagrangian consisting of spinor fields. Using this formula we determine the energy - momentum tensor for massive fields of arbitrary spin
in a uniform manner. Our result includes the already known energy - momentum tensors for Dirac and Proca fields as well as for real bosonic fields with s > 1 as special cases.
