Dear Experts,

I have generated the SPheno output of the default B-L-SSM model in SARAH. And the spectrum file "SPheno.spc.BLSSM" can be generated successfully with default GUT scale input parameter.

Then, I copy the low scale parameters in "SPheno.spc.BLSSM" to the "LesHouches.in.BLSSM_low", hoping to run the SPheno again with low scale input. But the following error occurs:
NaN appearing in solution of tadpole equations for BMuP

We have no idea which step could be wrong...

Thank you very much in advance.

Best regards,
Jinmian

Hi,

you need to fill the file with numbers. Only for the high scale input an example point is defined.

Cheers
