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 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 کاملNew Tools for Analyzing Quark Mixing
We present some new mathematical tools which help to derive information about the quark mass matrices directly from experimental data and to elucidate the structure of these mass matrices. Supported in part by NSF contract PHY-89-08495 2 email: [email protected]
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 کاملParametrization of the quark mixing matrix involving its eigenvalues
A parametrization of the 3 × 3 Cabibbo-Kobayashi-Maskawa matrix, V , is presented in which the parameters are the eigenvalues and the components of its eigenvectors. In this parametrization, the small departure of the experimentally determined V from being moduli symmetric (i.e. |Vij | = |Vji|) is controlled by the small difference between two of the eigenvalues. In case, any two eigenvalues ar...
