Dear All,

I was trying to run Vevacious for the model "B-L-SM". I got the following results ending with TypeError: fullTunneling() got an unexpected keyword argument 'phi' ,

Setting up the VevaciousRunner object took 0.00162 seconds.

Minimizing the one-loop potential, calculating the tunneling time or its upper bound, and printing the results took 3.26742 seconds.

Warning! "/home/smandal/packages/VEVA/Vevacious/MyResult.vout" was not produced!

Vevacious finished. Total running time was 3.27601 seconds.

I dont have any clue what is going wrong. Looking forward for your answer.

Hi,

Might it be that you are looking at a unbounded from below direction ? CT can't be used in that case.

Cheers.

Hi,

Maybe you are right. I attached the LesHouches.inBLSM file. When I increased the vXinput from 3.00E+03 to 3.500E+03, its working and I am getting the following results,

Well, the potential is a bit difficult to do at one loop numerically, it seems. MINUIT complains a lot about being unable to get to a minimum within its tolerances:
"
VariableMetricBuilder: Tolerance is not sufficient - edm is 0.00112391 requested 1e-05 continue the minimization
VariableMetricBuilder: warning: no improvement in line search
VariableMetricBuilder: finishes without convergence.

FunctionMinimum is invalid.
The MINUIT wrapper threw an exception:

So the tree-level minimum at vH -> ( 247.654147 ), vX -> ( 2500.0 ) seemed to be very problematic for MINUIT. Vevacious has no better idea than to just take the tree-level minimum as a substitute in that case, but since MINUIT tried to roll away from there, it is probably not anything like a minimum, so CosmoTransitions is probably trying to calculate tunneling for an invalid set-up, and failing.
