vevacious model files created by sarah

[Algernon]

Dear Florian:

The following is my question and Ben‘s answer. Now i need your help ?


MY QUESTION:
Dear:

1. i created the NMSSM.vin by SARAH.

2. i created the SPheno.spc.NMSSM by sarah-spheno.

3. i run ./Vevacious.exe VevaciousInitialization.xml

4. Unfortunately， some error happens :

warnings.warn(msg, UserWarning)
Traceback (most recent call last):
File "./Vevacious.py", line 23, in <module>
import VevaciousParameterDependent as VPD
File "/home/Vevacious/bin/VevaciousParameterDependent.py", line 667, in <module>
MassesSquareds = [ [ MassesSquared1, 2*valueDimensions, 1.5, "scalar" ],
NameError: name 'valueDimensions' is not defined

Minimizing the one-loop potential, calculating the tunneling time or its upper bound, and printing the results took 0.523029 seconds.

Warning! "../NMSSM/MyResult_NMSSM.vout" was not produced!


Could you please give me some hints?

Best wishes!




BEN'S ANSWER:
Dear Algernon,

I'm sorry, this is really a SARAH issue. In the .vin file, there should only be plain numbers between the quote marks following factor=.
E.g. it would be valid to have
factor="8"
or
factor="1"
but not
factor="2*alpha"
or
factor="Exp[Log[Pi]]"
so somehow SARAH is not evaluating valueDimensions as a number, so is not putting a number in the file instead of "2*valueDimensions".

MY QUESTION:

Dear Ben:

I am confused about this parameter. Where i can find the defintion of the valueDimensions? Just in this NMSSM.vin， what's the Specific value i should set?
Thanks a lot!


Cheers,
Algernon


BEN'S ANWER:

Dear Algernon,

I am also confused about this parameter. It is a SARAH issue. SARAH questions need to be answered by Florian Staub.

Ben

Hi,

sorry for the delayed reply but I'm on vacation and I also don't have any Mathematica here to check what goes wrong. According to the description of your problem, it seems that the parameter "valueDimensions" is not set correclty. Can you try to edit init.m, line 484ff

Code: Select all

_,
	If[Fields[[i,j2+3]]==1,
	valueCasimir=0;
	valueDynkin=0;
	valueGenerator= 0;
	valueDyn={0};
	valueDynSF={0};,

and add

Code: Select all

valueDimensions=1;

(somewhere before the last come shown here, e.g. for instance between valueDyn and valueDynSF).

Cheers,
Florian

Dear Florian:


I have checked all this according to your suggestion. The NMSSM.vin Seems to changeless. The parameter "valueDimensions" still can't get the Specific value in NMSSM.vin. And the error still happens when runing ./Vevacious.exe VevaciousInitialization.xml.



Best wishes!

Ok, Sorry for that. Then the easiest for the moment, until I can check what goes wrong, is to modify the file by hand: calculate the correct factor by your own by using 3 for valueDimensions in case of coloured states (Fd,Fu,Sd,Su) and 1 for uncoloured ones.

Finally, here is the patch.

Thank you for the patience.
