Predictions for neutralKandBmeson physics

Using supersymmetric grand unified theories, we have recently invented a framework which allows the prediction of three quark masses, two of the parameters of the Kobayashi-Maskawa matrix, and $tan\beta$, the ratio of the two electroweak vacuum expectation values. These predictions are used to calculate $\epsilon$ and ${\epsilon }^{\prime }$ in the kaon system, the mass mixing in the $B_d^0$ and $B_s^0$ systems, and the size of $\mathrm{CP}$ asymmetries in the decays of neutral $B$ mesons to explicit final states of given $\mathrm{CP}$.
