Problem of the Complete Measurement for CP-violating Parameters in Neutral B-meson Decays

Abstract

Phenomenological CP-violating parameters in decays of neutral B-mesons are discussed. Special attention is given to the degree of their measurability. We emphasize important role of the sign of $\Delta m_B$ and suggest how it could be determined experimentally.
