Is the fermion mass Lagrangian term imaginary instead of real?
This seems to be an absurd question, but bear with me.
In quantum field theory, the Dirac fermion mass Lagrangian term reads
$$
m\bar\psi \psi = m(\bar\psi_L \psi_R + \bar\psi_R \psi_L) = m(\psi_L^\da …

Can you quantize Grassmann-even superfields in the same fashion as Boson fields?
In a related Phys.SE question about supersymmetric Lagrangian
$$
\mathcal{L} = - \frac{1}{2} (\partial S)^2 - \frac{1}{2} (\partial P)^2 - \frac{1}{2} \bar{\psi} \partial\!\!\!/ \psi,
$$
the fields $S …
