摘要：

The origin of neutrino masses and mixings is an important topic in high energy physics. In the present work, two mixing schemes namely Bi-maximal (BL) and Tri-bimaximal (TBM) mixings which are derived from mu-tau symmetric neutrino mass matrix, are examined after taking corrections from charged lepton sector. While tri-bimaximal mixing with appropriate charged lepton correction, is in good agreement with latest observations, the Ri-maximal mixing after taking charged lepton correction, fails to agree completely with observation. A new scheme called strict Bi-large (BL) mixing scheme is introduced in place of BM mixing scheme.The BL scheme works very well in complete agreement with data. Some of the unsettled issues in neutrino physics are outlined for further investigations.
