\subsubsection{Two flavor oscillations}  Since $U_{\alpha \beta} is a unitary matrix, in the case of two flavor oscillations, it can be represented by a rotation matrix  \begin{equation}  U_{\alpha \beta} = \begin{bmatrix}  \cos \theta & \sin \theta \\  -\sin \theta & \cos \theta \\  \end{bmatrix}  \end{equation}
