SPheno null result for dirac neutrino

Post by shivamg » 23. Apr 2019, 12:36

Dear Florian,

I am writing a dirac mass term for neutrino in SM. But in Spheno output, i am getting massless neutrinos. Same heppens, when i checked B-L-SM model's Spheno output. I have attached all the model files. I need your assistance. Please check with it.

Thanks and regards,
Shivam Gola

Did you check in Mathematica that the analytical expression for the mass is correct?

Yeah it is giving correct expression. But in SPheno its not giving expected non zero mass. I need your assistance. Please check with it.

Hi, my problem is solved, i am using SARAH 4.14.1, so one need to change flag no.55 from 0 to 1 in Leshouche.in file.

Thanks you.
