Abstract
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 mt200 GeV from Vcb0.06. One gets maximal CP violation, and the relations -Vub/Vcb-= mu/mc, -Vtd/Vcb-= md/ms, and -Vts-=-Vcb- 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 MZ), and the possibility of a vanishing Vub and its impact on CP violation. © 1990 The American Physical Society.
