Sign conventions

  1. Mar 12, 2013 #1
    Does anyone know if the sign convenmtion from the metric tensor is linked to the sign convention in the Dirac equation. i.e is it possible to have a dt^2 - dX^2-dY^2-dZ^2 metric,

    with a (-,+,+,+) convention for the Dirac equation?

    unfortunately i agree but i have been working through. http://arxiv.org/abs/hep-ph/0003045v3 and they seem to define the hamiltonian in a different way to the metric.
