Phenomenology of two texture zero neutrino mass in left-right symmetric model with
We have done a phenomenological study on the neutrino mass matrix
favoring two zero texture in the framework of left-right symmetric model (LRSM)
where type I and type II seesaw naturally occurs. The type I seesaw mass term
is considered to be following a trimaximal mixing (TM) pattern. The symmetry
realizations of these texture zero structures has been realized using the
discrete cyclic abelian group in LRSM. We have studied six of the
popular texture zero classes named as A1, A2, B1, B2, B3 and B4 favoured by
neutrino oscillation data in our analysis. We basically focused on the
implications of these texture zero mass matrices in low energy phenomenon like
neutrinoless double beta decay (NDBD) and lepton flavour violation (LFV) in
LRSM scenario. For NDBD, we have considered only the dominant new physics
contribution coming from the diagrams containing purely RH current and another
from the charged Higgs scalar while ignoring the contributions coming from the
left-right gauge boson mixing and heavy light neutrino mixing. The mass of the
extra gauge bosons and scalars has been considered to be of the order of TeV
scale which is accessible at the colliders.Comment: 33 pages, 21 figures, 10 table
