Dear readers,

I have tried to install Vevacious 1.2.02 on my system, but I am running into problems. Most of them I have solved, but there is one that I cannot seem to understand.

I have tried to run a standard example, using the xml file provided in the attachment. The error that I get is the following:

--------------------------------

Then I tried to replace the line

vcs = VPD.Vevacious(
EffectivePotential = VPD.LoopAndThermalCorrectedPotential )
to

vcs = VPD.Vevacious(
EffectivePotential = VPD.TreeLevelPotential )

and put
vcs.shouldDoThermalCalculations = False

in the Vevacious.py file.

And then I get:

Could you help me solve this error? Note that for the example SLHA file modifying the functions in Vevacious.py did solve the problem, but it did not for my slhafile (also in the appendix). This slhafile was generated with via the chain softsusy - feynhiggs - susyhit.

Kind regards,
Melissa

Hi,

I don't think that the SusyHit output is compatible with your Vevacious file. You are using: while the SusyHit output is in the SLHA 1 format. There are model files using SLHA1 conventions. However, I must say that I don't know if those were ever used in practice.

Cheers,
Florian

Hi Florian,

I indeed thought this was the issue as well, but I forgot to mention that I tried to modify this to slha1 but that did not solve my problem. Same issue arises.

Cheers,
Melissa

Hi Florian,

I believe it has to do with an upgrade of scipy. I had installed Vevacious before, then everything worked for me just fine (also on susyhit files using the slha1 model file). But then I tried to install Vevacious on another cluster. I had to modify in cosmotransistions the file finiteT.py and add import scipy.misc, otherwise scipy.misc.factorial was not recognized. Since I made this change, the problem appeared. Is this useful?

Cheers,
Melissa

Hi,

unfortunately, I haven't installed Vevacious myself for some time on a new machine. So, I didn't run in that problem before.
What version of CT do you use?

Cheers,
Florian

I am using CT 2.0.3, downloaded from https://github.com/clwainwright/CosmoTransitions.

Another change I made compared to the previous time I installed Vevacious is that I am now using iminuit instead of pyminuit. Do you know whether that could affected anything?

Hi Florian,

I was trying to use Vevacious for the model B-L-SM model and I also got the same error " unexpected keyword argument 'phi' " ,

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

Hi,

Since the error appears already before CT is called, when you use the loop potential, it might be a problem with the minimizer.
So, I worry that there are two sources of problems at the end. Maybe, it's worth to try to contact the CT author regarding the problem with scipy. He has left physics but obviously still works on the code from time to time. Since I can't reproduce the errors on my machine, it's hard to give any good advice.

This seems to be another problem. Could you please open a new thread for that. I'll delete this post here the next days.

Florian

Hi Florian.

Thanks, I will contact him. Another question I have is regarding the .vin model files. It extracts HMIX[2] from the slha file provided, but in the example SLHA file CMSSM_CCB.slha.out, there is no HMIX[2] entry. How is this dealt with?

Cheers,
Melissa
