Hi Florian,

I have only 3 vevs, because the last one has been commented.
Look forward to your reply.

Thanks very much!

Hi Florian,

After I add
Tad1Loop[x_Integer]:=0; after ParametersToSolveTadpoles, the problem doesn't solved.

It seems that it's not a problem of 1-loop calculation.

Hi Florian, I have two problems in writing a new 331 model. First, suppose that Q=T3+beta*T8+x*I, where x is the U(1) charge, the two models implemented in SARAH program, the 331v1 and 331v2 models, have different conventions in choosing beta. The first is -1/sqrt(3), and the second is sqrt(3). How ...

Hi Florian,

Thank you, I will try it.

Hi Florian, Sorry for disturbing you.. In my model, all is okay when I making ufo with sarah in mathematica( with no error or warning), but after I generate and output a process in madgraph, it says, fail to handle expression: {...some long expression...}, type()=<type 'str'> . I don't know where is...

Hi Florian,

Thanks for your reply very much!

Hi Florian, Thanks for your quick reply. 1.The first question has been solved after using the function WriteTemplatesParFiles[], which is a very useful comment. The second question occured when I try to run SPheno in Sarah. 2a. One problem of the second questions is, the tadpole equations, which hav...

Hi Florian, Sorry for bothering you again.. I have two questions about sarah: 1.When I makeufo with Sarah, there is a waring like Creating particle List "Part specification None[[1]] is longer than depth of object. I don't know where is wrong, and how can I fix it? 2.Another question is, is there an...

Hi Florian, I have a problem in solving tadpole equations. The Higgs I wrote is DEFINITION[EWSB][VEVs]= { {Hd1, {vd1, 1/Sqrt[2]}, {sigmad1, I/Sqrt[2]}, {phid1, 1/Sqrt[2]}}, {Hd2, {vd2, 1/Sqrt[2]}, {sigmad2, I/Sqrt[2]}, {phid2, 1/Sqrt[2]}}, {HT, {vh, 1/Sqrt[2]}, {sigmah, I/Sqrt[2]}, {phih, 1/Sqrt[2]}...
