Description

An $A_5$ discrete symmetry group is used to construct a neutrino mass model that can reproduce deviation from golden ratio mixing. Here, the neutrino masses are obtained through Type-I see-saw mechanism. The neutrino masses and mixing patterns predicted by the model can explain the current data with good accuracy. In this work, the correlation between neutrinoless double beta decay parameters $|m_{\beta \beta }|$ and neutrino oscillation parameters are also investigated. The analysis is consistent with latest cosmological bound $\mathrm{\Sigma }{m}_i\le$ 0.12 eV.
