Low-energy formulas for neutrino masses with $\tan \beta$-dependent hierarchy

Abstract

Using radiative correction and seesaw mechanism,we derive analytic formulas for neutrino masses in SUSY unified theories exhibiting, for the first time, a new hierarchial relation among them.The new hierarchy is found to be quite significant especially for smaller values of $\tan \beta$.
