Abstract

We discuss possible signatures of the tree level FCNC, which results from the non-unitarity of CKM matrix. We first define the unitarity step-by-step, and possible test of the non-unitarity through the 4-value-KM parametrization. We, then, show how the phase angle of the unitary triangle would change in case of the vector-like down quark model. As another example of tree FCNC, we investigate the leptophobic Z′ model and its application to the recent Bs mixing measurements.
