Narrow Results

Recently, the precise observations have yielded values for the neutrino mixing angles, denoted as ${\theta }_{12}$ and ${\theta }_{13}$. Therefore, constructing a neutrino mixing model capable of accurately reflecting these measurements is crucial. In this paper, we propose a novel neutrino mixing model similar to the trimaximal mixing model. Unlike the trimaximal model that falls short of concurrently replicating the best-fit values of ${\theta }_{12}$ and ${\theta }_{13}$, our proposed mixing model has the ability to simultaneously reproduce the best-fit values for both 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.
