In the presence of such NSI parameters involving the $e-\\mu$ ($\\varepsilon_{e\\mu}$) and $e-\\tau$ ($\\varepsilon_{e\\tau}$) flavors, the $\\nu_\\mu \\to \\nu_e$ and $\\bar\\nu_\\mu \\to \\bar\\nu_e$ appearance probabilities in long-baseline experiments acquire an additional interference term, which depends on one new dynamical CP-phase $\\phi_{e\\mu/e\\tau}$.
