Issues with critical temperatures and minimum at T=0 about cosmotransitions HOT 5 CLOSED

Can You figured out what happened to the findMinimum(T=0)?

No, at the end no...

The minimum mismatch is just that any numerical minimization has a numerical tolerance. findMinimum uses scipy.optimize.fmin (see generic_potential.py), which has a default tolerance of 1e-4 (see https://docs.scipy.org/doc/scipy/reference/generated/scipy.optimize.fmin.html)

Regarding the second question. I know this is a bit late, but may be it will be helpful to people in the future. Your CT model implements the following potential:

As you saw, CT found the correct minimum. I am not sure how you got the potential in your image.
May be it is the choice of the renormalization conditions? The CW paper specifies 2 and 4 point functions at p=0, whereas CT assumes MSbar renormalization (the choice of c coefficients boson_massSq to be 3/2 - btw these should be different for transverse and longitudinal gauge boson polarizations)

After reading CT documentation, I understood that scaler masses can be put in masssq in test1model.py file but I am not able to understand how to put w boson and z boson masses and their thermal corrections.

The second thing is I was trying to change m1 and m2 expressions in bosonmasssq in generic potential.py class but there is no change in result for critical and nucleation temperature.

The third is z2 symmetry for the second field is it correct if vev for the second field is considered zero in tree-level potential itself.

it would be a great help.

thanks
