Flavored leptogenesis with quasi degenerate neutrinos in a broken cyclic symmetric model
Biswajit Adhikary, Mainak Chakraborty, Ambar Ghosal
Cyclic symmetry in the neutrino sector with the type-I seesaw mechanism in the mass basis of charged leptons and right chiral neutrinos (, ) generates two fold deg…
Maximal zero textures of the inverse seesaw with broken symmetry
Biswajit Adhikary, Ambar Ghosal, Probir Roy
The inverse neutrino seesaw, characterised by only one source of lepton number violation at an ultralight (keV) scale and observable new phenomena at TeV energies accessible to…
Masses, mixing angles and phases of general Majorana neutrino mass matrix
Biswajit Adhikary, Mainak Chakraborty, Ambar Ghosal
General Majorana neutrino mass matrix is complex symmetric and for three generations of neutrinos it contains 12 real parameters. We diagonalize this general neutrino mass matrix a…
, symmetry breaking and neutrino Yukawa textures
Biswajit Adhikary, Ambar Ghosal, Probir Roy
Within the type-I seesaw and in the basis where charged lepton and heavy neutrino mass matrices are real and diagonal, symmetric four and three zero neutrino Yukawa textures a…
Scaling ansatz, four zero Yukawa textures and large
Biswajit Adhikary, Mainak Chakraborty, Ambar Ghosal
We investigate 'Scaling ansatz' in the neutrino sector within the framework of type I seesaw mechanism with diagonal charged lepton and right handed Majorana neutrino mass matrices…
Neutrino masses, cosmological bound and four zero Yukawa textures
Biswajit Adhikary, Ambar Ghosal, Probir Roy
Four zero neutrino Yukawa textures in a specified weak basis, combined with symmetry and type-I seesaw, yield a highly constrained and predictive scheme. Two alternately viabl…
'Mu-Tau' symmetry, tribimaximal mixing and four zero neutrino Yukawa textures
Biswajit Adhikary, Ambar Ghosal, Probir Roy
Within the type-I seesaw framework with three heavy right chiral neutrinos and in the basis where the latter and the charged leptons are mass diagonal, a near `mu-tau' symmetry in…
