Exponential and Wolfenstein parametrizations of the CKM matrix
- 47 Downloads
The derivation of the Wolfenstein form of the Cabibbo-Kobayashi-Maskawa matrix\(\hat V\) from exponential parametrization is discussed. It is proved that at orderλ3 a one-to-one correspondence exists between the Wolfenstein parameters and the entries of matrix\(\hat A\) that generates\(\hat V\). The importance of exponential parametrization in generating mass matrices is analysed. The usefulness of the entries of\(\hat A\) in analysing the experimental data is also discussed.
