5 Apr 2012 | | Abstract: | The CKM matrix describing quark mixing with three generations can be
parameterized by three mixing angles and one CP violating phase. In most of the
parameterizations, the CP violating phase chosen is not a directly measurable
quantity and is parametrization dependent. In this work, we propose to use
experimentally measurable CP violating quantities, $alpha$, $eta$ or
$gamma$ in the unitarity triangle as the phase in the CKM matrix, and
construct explicit $alpha$, $eta$ and $gamma$ parameterizations.
Approximate Wolfenstein-like expressions are also suggested. | | Source: | arXiv, 1204.1230 | | Services: | Forum | Review | PDF | Favorites | |
