Spontaneous CP Violation in the Left-Right-Symmetric Model
We investigate the pattern of CP violation in \Kd, \Bd and \Bs mixing in a symmetrical \model model with spontaneous CP violation. Performing a careful analysis of all relevant restrictions on the model's parameters from $\Delta M_K$, $\Delta M_{B_d}$, $\Delta M_{B_s}$, $\epsilon_K$, the sign o...

description | We investigate the pattern of CP violation in \Kd, \Bd and \Bs mixing in a symmetrical \model model with spontaneous CP violation. Performing a careful analysis of all relevant restrictions on the model's parameters from $\Delta M_K$, $\Delta M_{B_d}$, $\Delta M_{B_s}$, $\epsilon_K$, the sign of \ee and the mixing-induced CP asymmetry in \goldd, we find that the mass of the right-handed charged gauge-boson, $M_2$, is restricted to be in the range 2.75 to 13$ $TeV, and that the mass of the flavour-changing neutral-Higgs bosons, $M_H$, must be between 10.2 to 14.6$ $TeV. We also find that the model, although still compatible with present experimental data, cannot accomodate the SM prediction of large CP violation in \goldd, but, on the other hand, predicts a large CP-asymmetry of ${\cal O}(40%)$ in \golds. These specific predictions make it possible to submit the model to a scrupulous test at B factories and hadron colliders. |
