| contents | The $B$-Mesogenesis model explains the matter-antimatter asymmetry and leads to the right amount of dark matter in the Universe. In particular, this model predicts new decay channels of the $b$ quark. We investigate the modification of inclusive $b$-hadron decay rates and of the lifetimes of different $B$ mesons due to these new decay channels and compare our results with available predictions for exclusive $B$ meson decays. We find a small surviving parameter space where the $B$-Mesogenesis model is working and which has not been excluded by experiment. Experimental investigations in the near future should be able to test this remaining parameter space and thus either exclude or confirm the $B$-Mesogenesis model. |
