The remaining constraints of unitarity of the CKM-matrix can be written in the form For any fixed and different i and j, this is a constraint on three complex numbers, one for each k, which says that these numbers form the sides of a triangle in the complex plane. There are six choices of i and j (three independent), and hence six such triangles, each of which is called a unitary triangle. Their shapes can be very different, but they all have the same area, which can b… WebThe CKM matrix is known to be unitary. Now, is it just found experimentally? Is the following idea correct?
