Re: dose tree-level results in effective potential incorporate loop effects?

Many thanks.
So the second derivative of the effective potentail with respect to the
field phi gives phi's physical mass which is scale independent, since
there are no longer loop diagrams here?
The second derivative is usually a polynomial of the parameters which
is scale dependent. So if the second derivative is the physical mass,
it implies that there are some automatic cancellations between the
scale dependent quatities in the polynomial?
