comment Lorentz invariance and the vacuum expectation value of fields with spin > 0
Okay, I have too many questions now! So you used vector.vector to produce a scalar and showed this will be zero due to Lorentz invariance. What about chiral condensates where you have $<\bar{\psi} \psi> \neq 0 $?

Thanks Arnold, but can I ask two silly questions before I attempt the spinor case. Why did you choose a space-like vector to dot it with A(0)? Is this how a spin 1 field is minimised in general?

Hi David, I asked both together because I read them in the same sentence. So I would like to understand how the whole picture fit together. Is that Ok?
