$\mathit CP$ VIOLATION PARAMETERS in ${{\mathit B}_{{{s}}}^{0}}$

$\vert \lambda \vert $ ( ${{\mathit b}}$ $\rightarrow$ ${{\mathit c}}{{\overline{\mathit c}}}{{\mathit s}}$)

INSPIRE   PDGID:
S086LAM
$\lambda $ = q/p$\cdot{}{{\mathit A}_{{{f}}}}/{{\overline{\mathit A}}_{{{f}}}}$ is a phase-convention-independent observable quantity for the final state ${{\mathit f}}$. See the review on "$\mathit CP$ Violation in the Quark Sector" for details.
