摘要: Abstract The flavor changing neutral current decay of the Z0 boson into charge 2 3 quarks in standard three generation SU(2)L × U(1) theory electroweak interactions has been studied. This process occurs first at one-loop order, where it calculated without approximation. possibility producing as yet undiscovered top quark by this considered. branching ratios are extremely small, independent mass and plausible mixing matrices if there generations, making unlikely that will be produced mechanism. However, a massive fourth bottom could increase rates.
