$\mathit CP$ impurity in ${{\mathit B}_{{{s}}}^{0}}$ system.

“OUR EVALUATION” is the result of a fit to ${{\mathit B}_{{{d}}}}$ and ${{\mathit B}_{{{s}}}}$ $\mathit CP$ asymmetries, which includes the ${{\mathit B}_{{{s}}}}$ measurements listed below and the ${{\mathit B}_{{{d}}}}$ measurements listed in the ${{\mathit B}_{{{d}}}}$ section, and takes into account correlations between those measurements.
