TOP QUARK MASS AND THE FOURTH GENERATION OF QUARK

Abstract

To explain CP violation in Kaon system in the light of the recently measured b-lifetime within the framework of three generations of quarks, the top quark mass has to be greater than 50GeV if the current algebra value of the factor BK is adopted and |'/| < 0.01. In this letter a fourth generation of quark is considered which can fit the present experimental data on CP violation, and KL → μ+μ- decay rate for top quark mass is around 40 GeV. The mass of the new charge 2/3 quark is predicted to be over 100 GeV.
