Mass terms Phenomenologically, lagrangian mass terms can be understood as terms describing “transitions” between right (R) and left (L) handed states in the electroweak sector. For a given minimal, Lorentz invariant set of 4 fields (), we have the components … Continue reading
The current Standard Model of elementary particles and interactions supposes the existence of 3 neutrino species or flavors. They are neutral, upper components of “doublets” with respect to the group, the weak interaction group after the electroweak symmetry breaking, and … Continue reading
This new post ignites a new thread. Subject: the Science of Neutrinos. Something I usually call Neutrinology. I am sure you will enjoy it, since I will keep it elementary (even if I discuss some more advanced topics at some … Continue reading
