comment Pauli-Villars (PV) regularisation breaks supersymmetry. How to see that?
Thanks! So can I ask then, is the PV regulator enough to cancel divergences? If not, then why?

Ok, thanks for your answer. The reason for the confusion is that I'm confused myself. I was following the PV scheme without knowing the physics behind it :/ But I think I'm getting a feeling of what the PV regulator does. Thanks again to you and to Zohar Ko whom I annoyed :p

No, I was asking about the PV regularisation. Maybe some time later I'll ask about DM. :p

I did similar calculation, as an exercise. I used PV and I got a similar result. But then, someone was saying something about PV regulator breaking susy and I was lost. :p Also, I didn't understand your answer.

Because I took the equation from there. Umm, Ok let's say: Does the Pauli-Villars regularisation break supersymmetry? And how to see that?

comment Ricci scalar for a diagonal metric tensor.
thank you very much for your clear and very helpful answer! I've been practicing your method on a simple case. And I'm really pleased. However, I noticed that if I am to get the correct result for $\Gamma$, I need to divide by the entry that corresponds to the upper index of $\Gamma$. For example, in your equation for $\Gamma^\mu_{\nu\sigma}$, I put $$...\frac{A^\prime}{2A}l^0_{11} ... -\frac{\dot{B}}{2A} l^0_{11}...$$ and I get correct results. Am I doing it right?
