• No valid parameters found in SSP scan

Hi Florian,

It's me again, who asked this question:

http://www.stauby.de/sarah_userforum/vi ... ?f=4&t=214

About LesHouches.in.MSSM.low file, that stop unless I close (Calculate one loop masses) ..

Actually I closed this option (and asked as before if weather this 'd make problems or not ) and generated the Spheno.spc.low file , then I tried to make non-universal scan in SSP on for instance M2 or mu , but the scan always gives:
No valid parameter point found during scan

I filled Example.m file or (SSP_Template_lowScaleInput.m) from LesHouches.in.MSSM.low , but indeed I don't know what is the problem :

I attached here the three files, I appreciate if you tell me what is the problem, actually I tried to search in Block SPhenoInput options , but it always give no valid parameter point.

Thanks,
Astro

Hi,

1) If you use MODSEL[0]=0, (low-scale input), you shouldn't put flag 31

2)

Code: Select all

{{400},{Value->1.00000000*10^1}},
{{401},{Value->1.00000000*10^3}}

These numbers need to be smaller than 1, i.e. the minus in the exponent is missing.

Cheers
Florian

Hi Florian,

I rewrite this , but still have no valid parameters points, please can you look at the attached files now , actually I tired last days to find out what else can make problem while scan at low scale but can't find out ..

I'm fixed the problem of negative squared mass error when running LesHouches.in.MSSM.low, by changing the MA2input to :7.69841686*10^6 rather than the default value (7.69841686*10^3).

Thanks,
Astro

Hi,

if I use the standard option as written by SARAH in the SSP template, your input runs fine for me. So, there is some incompatibility with your settings. Actually, I don't what you want exactly to do and why you put all the additional flags. I would suggest, just go back to the standard settings.

Cheers
Florian

Hi,

if I use the standard option as written by SARAH in the SSP template, your input runs fine for me.

You mean the scan give valid points ? it 'd be great. What I did is repeating the whole process form the beginning, made new LesHouches.in.MSSM.low file and generated spc.low file and filled the SSP. templet as default, please see the attached one, it's exactly as default except adding the missing variables, and kept [SPhenoInput] block as it's, but still there is no valid input parameters when I make scan on m2 or mu !

Appreciate your help ..

Hi,

I meant the SSP template written by SARAH. There you find for the low-scale version

Code: Select all

DEFINITION[a_][SPhenoInput]={ 
{{1},{Value->-1}}, (* error level *)
{{2},{Value->0}},  (* SPA conventions *) 
{{11},{Value->1}}, (* Calculate widhts and BRs *)
{{12},{Value->0.0001}}, (* minimal BR to write out *) 
{{13},{Value->1}}, (* Enable 3-body decays *) 
{{34},{Value->0.0001}}, (* precision of masses *) 
{{38},{Value->2}}, (* 1/2 - Loop RGEs *) 
{{51},{Value->0}}, (* Switch to CKM matrix *) 
{{55},{Value->1}}, (* 1 - Loop masses *)
{{57},{Value->1}}, (* low energy constraints *)
{{65},{Value->1}}, (* Solution tadpole equation *)
{{75},{Value->1}}, (* Write WHIZARD files *) 
{{76},{Value->1}},  (* Write HiggsBounds files *) 
{{86},{Value->0.}},  (* Maximal width to be counted as invisible in Higgs decays; -1: only LSP *) 
{{530},{Value->1.}}  (* Write Blocks for Vevacious *) 
};

Cheers,
Florian

Yes, that what I used, the inputs of Example2.m file are taken from SSP_templet made by SARAH, for instance :

Code: Select all

DEFINITION[a_][SPhenoInput]={ 
{{1},{Value->-1}}, (* error level *)
{{2},{Value->0}},  (* SPA conventions *) 
{{11},{Value->1}}, (* Calculate widhts and BRs *)
{{12},{Value->0.0001}}, (* minimal BR to write out *) 
{{13},{Value->1}}, (* Enable 3-body decays *) 
{{34},{Value->0.0001}}, (* precision of masses *) 
{{38},{Value->2}}, (* 1/2 - Loop RGEs *) 
{{51},{Value->1}}, (* Switch to CKM matrix *) 
{{55},{Value->0}}, (* 1 - Loop masses *)
{{57},{Value->1}}, (* low energy constraints *)
{{65},{Value->1}}, (* Solution tadpole equation *)
{{75},{Value->0}}, (* Write WHIZARD files *) 
{{76},{Value->0}},  (* Write HiggsBounds files *) 
{{86},{Value->0.}},  (* Maximal width to be counted as invisible in Higgs decays; -1: only LSP *) 
{{550},{Value->1}},  (* Calculate Fine-Tuning *) 
{{530},{Value->1.}} (* Write Blocks for Vevacious *)
};

Best,

Are you sure that your paths are correct, i.e. that SPheno is correctly called?

Cheers
Florian

Yes, because it works probably (make scans) when I try for instance Example1_GridScan_testSPheno.m file found in SSP/Input folder with LesHouches.in.MSSM and spc files at Gut scale .

Best,
Astro

Hi Florain,

I also made another check, as I make scan in Example2.m file on mu from 1 to 5000 , that which SSP says there is no Valid parameters points at this range , I set the value of mu to say 1 or 5000 in LesHouches.in.MSSM.low file and then run it in SPheno . I found SPheno generates the spc file probably and didn't show any messages ..

Thanks,
Astro
