Mass differences of the $K^0 - \bar{K}^0$, $B_s^0 - \bar{B}_s^0$ and $D^0 - \bar{D}^0$ systems in the minimal 3-3-1 model

摘要

In the present work we calculate the tree-level contribution of the minimal3-3-1 model to the mass differences in the $K^0 - \bar{K}^0$, $B_s^0 -\bar{B}_s^0$ and $D^0 - \bar{D}^0$ systems. We also present an analyticalsolution for the mass eigenstates of the neutral CP-even scalars and anumerical method to find the matrices that diagonzalize the quark massmatrices.
