### Description

We analyze the effect of the Dark-large mixing angle (DLMA)
solution on the effective Majorana mass ($m_{\beta\beta}$) governing neutrino-less double beta decay ($0\nu\beta\beta$) in the presence of a sterile neutrino.
We consider the 3+1 picture, comprising of one additional sterile neutrino.
We have checked that the MSW resonance in the sun can take place in the DLMA parameter space in this scenario. Next we investigate how the values of the
solar mixing angle $\theta_{12}$ corresponding to the DLMA region alter the
predictions of $m_{\beta\beta}$ by including a sterile neutrino in the analysis.
We also compare our results with three generation cases for both standard large mixing angle (LMA) and DLMA. Additionally, we evaluate the discovery sensitivity of the future ${}^{136}Xe$ experiments in this context.

### Mini-abstract

Here we analyze the implication of DLMA solution for neutrino-less double beta decay in 3+1 scheme.
