CKM quark - mixing matrix 1 11 . THE CABIBBO - KOBAYASHI - MASKAWA QUARK - MIXING MATRIX
Revised 1999 by F.J. Gilman (Carnegie-Mellon University), K. Kleinknecht and B. Renk (Johannes-Gutenberg Universität Mainz). In the Standard Model with SU(2) × U(1) as the gauge group of electroweak interactions, both the quarks and leptons are assigned to be left-handed doublets and right-handed singlets. The quark mass eigenstates are not the same as the weak eigenstates, and the matrix relat...
متن کاملComments on the Characteristic Measurables of the Quark Mixing Matrix
Within the standard electroweak model we point out that the 3×3 matrix of quark mixing is characterized by three universal (rephasing-invariant) quantities: one of them for CP violation and the other two for off-diagonal asymmetries. Unitarity of the quark mixing matrix can in principle be tested through a variety of measurements which are irrelevant to the existence of CP -violating effects. P...
متن کاملDiscrete Symmetry and CP Phase of the Quark Mixing Matrix
A simple specific pattern of the two 3×3 quark mass matrices is proposed, resulting in a prediction of the CP phase of the charged-current mixing matrix VCKM , i.e. sin 2φ1(β) = 0.733, which is in remarkable agreement with data, i.e. sin 2φ1 = 0.728± 0.056± 0.023 from Belle and sin 2β = 0.722± 0.040± 0.023 from Babar. This pattern can be maintained by a discrete family symmetry, an example of w...
متن کاملPhysical renormalization condition for the quark-mixing matrix
We investigate the renormalization of the quark-mixing matrix in the Electroweak Standard Model. We show that the corresponding counterterms must be gauge independent as a consequence of extended BRS invariance. Using rigid SU(2)L symmetry, we proof that the ultraviolet-divergent parts of the invariant counterterms are related to the field renormalization constants of the quark fields. We point...
متن کاملNeutron β-decay and the quark-mixing CKM-matrix
Neutrons study a number of hot topics from the field of particle physics and cosmology: Recent measurements of various mixed American-British-French-GermanHungarian-Japan-Russian groups of researchers determine the strength of the weak interaction of the neutron, which gives us unique information on quark-mixing and the question of unitarity. Much to our surprise, with neutron-decay we find a d...
