Description
A novel scenario is presented within the Type-I seesaw
mechanism in which no other beyond Standard Model fields except three
heavy right handed neutrinos, have been considered. Light neutrino
masses around sub eV scale, could be possible at low seesaw scale around
TeV or even below that. At the leading order, 6x6 seesaw mass matrix
reproduces three massless neutrinos. The Dirac mass matrix with one loop
corrections, breaks that massless texture and it is possible to get
massive neutrinos. We have obtained the expression of mixing and Dirac
CP violating phase for light neutrino mass matrix with one loop
corrections. Only unknown parameters are the Yukawa couplings related to
right handed neutrinos and their masses. These parameters satisfy the
ATLAS, CMS experimental constraints.
