Relating the longBlifetime to a very heavy top quark

The long B lifetime is related to the heaviness of the top quark by a particular mass-mixing ansatz. The u-type quark mass matrix is of the Fritzsch form, while for the d type it is diagonal except in the d-s plane, which generates the Cabibbo rotation. We predict $m_t$≳200 GeV from $V_{\mathrm{cb}}$≲0.06. One gets ‘‘maximal CP violation,’’ and the relations ‖$V_{\mathrm{ub}}$/$V_{\mathrm{cb}}$‖= √$m_u$/$m_c$ , ‖$V_{\mathrm{td}}$/$V_{\mathrm{cb}}$‖= √$m_d$/$m_s$ , and ‖$V_{\mathrm{ts}}$‖=‖$V_{\mathrm{cb}}$‖ are close to exact. An interesting Wolfenstein pattern emerges. We discuss the viability and implications of having such a heavy top quark (such as lower $M_Z$), and the possibility of a vanishing $V_{\mathrm{ub}}$ and its impact on CP violation.
