There are two kinds of leptonic mass matrices M_{\nu} resulted out from Inverse seesaw mechanism. How do we realize differently while using them?

There are two leptonic mass matrices obtained while working in Inverse seesaw regime, 1. M\nu = {{0, mD, 0} ,{mDT, 0, M}, {0, MT, \mu}}, 2. M\nu = {{0, mDT, 0}, {mD, 0, MT}, {0, M , \mu}}. After...

What is the reason of the fact that the three flavors of neutrino behave similarly at extremely high energy(<10^12 GeV)?

At temperature T~ 10^12 GeV or above, lepton asymmetries that produced by the out of equilibrium decays of heavy neutrinos do not distinguish lepton flavors. If we go to lower temperature reign...

How the concept of accidental symmetry is used to accommodate a stable Dark Matter candidate?

We have come across several works , where some discrete symmetries is invoked for the stability of a potential DM candidate. That we do by assigning Z_n charges on the respective particles whom we...

What is the precise lepton no violating scale while working in Inverse Seesaw regime?

Text says that, the essence of the seesaw mechanism demands the lepton number violation at a high energy scale. As a result left handed neutrinos get tiny masses through the formula m_{\nu} =...
