Dear authors,
Thank you for accepting the request.
I am implementing the Alternative left right model.
I am confused how to write the term: Trace(\phi^\dagger \phi)(\chi_L^\dagger \chi_L + \chi_R^\dagger \chi_R).
Where, \phi--> a bidoublet and \chi_{L,R} --> doublet under SU(2)_L and SU(2)_R respectively.
Please help how to write it.

Hi,
you have to define a contraction struction like in the LRLR model which you can find in the Models directory.
