A bstract We study the zero textures of the Yukawa matrices in the minimal extended type-I
seesaw (MES) model which can give rise to∼ eV scale sterile neutrinos. In this model, three …

A bstract We discuss neutrino masses and mixing in the framework of a supersymmetric
model with an U (1) R symmetry, consisting of a single right handed neutrino superfield with …

We construct a B− L model with A 4× Z 3× Z 4 flavor symmetry that accounts for the recent 3+
1 active-sterile neutrino data. The tiny neutrino mass and the mass hierarchy are obtained …

Motivated by the recent resurrection of the evidence for an eV scale sterile neutrino from the
MiniBooNE experiment, we revisit one of the most minimal seesaw model known as the …

We propose new mixing schemes for (3+ 1) neutrinos which describe mixing among active-
active and active-sterile neutrinos. The mixing matrix in these mixing schemes can be …

We propose a non-renormalizable BL model with S 3× Z 4× Z 2 symmetry which successfully
accommodates the current active–sterile neutrino mixing in 3+ 1 scheme. The S 3 flavor …

The presence of a zero texture in the neutrino mass matrix can indicate the presence of an
underlying symmetry which can generate neutrino mass and mixing. In this paper, for the …

We classify all possible texture zeros in a light neutrino mass matrix in a diagonal charged
lepton basis by considering the Dirac nature of light neutrinos. For the Hermitian nature of …

Earlier studies of the influence of dark matter keV sterile neutrinos on neutrinoless double
beta decay concluded that there is no significant modification of the decay rate. These …

A bstract The type II seesaw mechanism for neutrino mass generation usually makes use of
one complex scalar triplet. The collider signature of the doubly-charged scalar, the most …
