### Description

In the poster, we have taken $L_e-L_\tau$ gauge symmetry to study neutrino phenomenology in the framework of type-(I+II) seesaw mechanism. In the model, three heavy right-handed neutrinos, a scalar singlet, and one scalar triplet are added to the Standard Model. As a result, the active neutrino-mass matrix has a two-zero $A_1$ texture which helps explain neutrino oscillation parameters like $\theta_{13}, \theta_{23}. \theta_{12},$ the sum of active neutrino masses etc. The model also explains neutrinoless double $\beta$ decay and lepton flavor violation with reasonable accuracy. The branching ratio of $\tau \rightarrow e \gamma$ and $\tau \rightarrow \mu \bar{\mu} \mu$ also stay well below the experimental upper bound.
