Modified trimaximal mixing for solar and reactor neutrino mixing angles

The trimaximal mixing scheme is one of the widely studied neutrino mixing schemes. However, the predicted solar neutrino mixing angle ${\theta }_{12}$ and the reactor neutrino mixing angle ${\theta }_{13}$ cannot simultaneously realize their best-fit values. To address this issue, a minimal modification to the trimaximal mixing scheme is proposed. The modified trimaximal mixing scheme can simultaneously predict the best-fit values of ${\theta }_{12}$ and ${\theta }_{13}$ using an additional real parameter introduced via the modification.
