How can you tell the spin of a particle by looking at the Lagrangian?

[QUOTE="BiGyElLoWhAt, post: 6823282, member: 496972"] Ahh ok. So Klein-Gordon is basically ##E^2 - p^2 = m^2## which is Lorentz invariant, which is why this is spin 0. If that's correct, this makes complete sense. So then is it the presence of the ##\bar{\psi}## in the EM Lagrangian that is the main difference between Dirac and ##U(1)_{EM}##? That doesn't seem to change how ##\psi## should actually change though, unless it's something that just drops out eventually. Thanks for the intuitive reply, that's effectively the type of answer I was looking for, I just wasn't sure if there was a clear cut and simply answer like that available. [/QUOTE]
