Hey, I would like to ask you: I need have Standard Model with right-handed neutrinos. This is the simplest extension of SM which contains the Dirac and Majorana neutrinos.(adsbygoogle = window.adsbygoogle || []).push({});

PR (right projection operator) coefficients should be nonzero. Is that enough? But what is their value? In the SM for the neutrinos interaction with the Z boson, the coefficients are respectively 1 / 2 and 0.

Do neutrinos further in this model are massless? What is the Lagrangian interaction with W and Z? Is there any name of this model? Are any papers about this model?

thanks for your reply:)
