Dear Florian, In a model with two U(1) gauge groups, I have tried to force one of the mixing parameters to zero assigning in parameter.m a dependence to zero: {gZZY, {Description -> "Identically zero gauge mixing coupling", LaTeX -> "g_{ZY}", Dependence -> 0, OutputName -> gZY}} I hoped this would c...

Hi! I fail to execute SPheno for our model in my computer (SPheno output generated by SARAH), but in my collague's computer it runs without errors. Here is the error message. SPheno-3.3.8 bin/SPhenoMyModel Calculating branching ratios and decay widths NaN appearing in solution of tadpole equations f...
