LOG#122. Basic Neutrinology(VII).

The observed mass and mixing both in the neutrino and quark cases could be evidence for some interfamily hierarchy hinting that the lepton and quark sectors were, indeed, a result of the existence of a new quantum number related to … Continue reading

LOG#121. Basic Neutrinology(VI).

Models where the space-time is not 3+1 dimensional but higher dimensional (generally dimensional, where n is the number of spacelike extra dimensions) are popular since the beginnings of the 20th century. The fundamental scale of gravity need not to be … Continue reading

LOG#120. Basic Neutrinology(V).

Supersymmetry (SUSY) is one of the most discussed ideas in theoretical physics. I am not discussed its details here (yet, in this blog). However, in this thread, some general features are worth to be told about it. SUSY model generally … Continue reading

LOG#119. Basic Neutrinology(IV).

A very natural way to generate the known neutrino masses is to minimally extend the SM including additional 2-spinors as RH neutrinos and at the same time extend the non-QCD electroweak SM gauge symmetry group to something like this:   … Continue reading

LOG#118. Basic Neutrinology(III).

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

LOG#117. Basic Neutrinology(II).

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

LOG#116. Basic Neutrinology(I).

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
