Hi Florian, SPheno works perfectly well for Yukawa couplings for which the eigenvalues of squared mass matrix of neutrino has positive eigenvalues. What modifications do I need to do for the set of Yukawas for which the mass squared eigenvalues are negative..... Also for certain set of Yukawas the m...

Thanks Florian,
It worked after doing "make cleanall"......
Thanks,

Hi Florian, Is there any such constraint that real part of Yukawa has to be larger than imaginary part? I have tried with following Yukawa's:- (1) Yv=diag(1E-01, i 1E-05, 1E-01) The error is "Nan appearing in CalculateMFv" (2) Yv=diag(1E-00, i 1E-05, 1E-01) The error is "Problem with RGE running.Err...

Thanks Florian, For your reply. I had compiled the linear seesaw after editing src/makefile . One interesting observation is that for MR set to zero the code is running for YVIN=diag{1.0E-01,1.0E-01,1.0E-01}. But when it is added to IMYVIN =diag{1.0E-01,1.0E-01,1.0E-01} Spheno is terminating with th...

Thanks Florian, For your reply. But there is a different error with real Yukawa. I have tried it with linear-Seesaw model files given in SARAH.....the same problem persists there even in real Yukawa case. In the real case the error is:- "Problem in RGE Running. Errorcode: -1006" While in case of ima...

Hi Florian, I am working in Type-I SeeSaw model with complex neutrino yukawa (Yv). I have done the necessary change that you have mentioned i.e. to edit src/Makefile: PreDef = -DGENERATIONMIXING After that I had made all the necessary things (switching to 2 the flag 5 of MODSEL and by adding the blo...
