Problem with low scale input files

[biswaranjan]

Hi,

When i tried to generate the SPheno spectrum files for BLSSM (or BLSSM-IS or MSSM) with the low scale input files which were generated by SARAH (e.g.LesHouches.in.BLSSM_low ), i get the following errors:

NaN appearing in solution of tadpole equations for mHd2: BLSSM_low
NaN appearing in solution of tadpole equations for Bmu: BLSSMIS_low
NaN appearing in CouplingcUFdGluSd: MSSM_low

i tried to modify the LesHouches.in.BLSSM_low referring the LesHouches.in.BLSSM, but then it shows

Mass spectrum converged, but negative mass squared present.

Why this problem is occuring? Can you please kindly suggest?

Thanks,
biswaranjan

hi,

did you check if the input files contains reasonable numbers for all entries or just zeros at placeholders?

Cheeers,
