mixing mass matrices in lanhep
thanks for your very useful forum.
I am trying to implement a model in lanhep which has to fields with mix masses. Due to tackle with this problem I have some questions.
1. At first these fields are in gauge basis, and we have to rotate them to mass eigen states. Now, which particles should we declare in lanhep? mass eigen states or gauge eigen states?
2.could we calculate and diagonalize mass matrix in another program and then use masses in lanhep?
3.regarding the manual to recognize mass matrix in lanhep we should declare it OrthMatrix statement. to provide this option we should firstmake a library by this command:
gcc -shared -o diag.so diag.c
but it didnt say that how should we make this library and how can we find or write diag.c file ?
Its very kind of you if you have a simple example of using mass mixing matrices or advice to solve this problem.
