Query: D^0-\bar{D}^0 Mixing and CP Violation in Neutral D-meson Decays   D^0-\bar{D}^0 mixing at the detectable level or significant CP violation in
the charm system may strongly signify the existence of new physics. In view of
the large discovery potential associated with the fixed target experiments, the
B-meson factories and the \tau-charm factories, we make a further study of the
phenomenology of D^0-\bar{D}^0 mixing and CP violation in neutral $D$-meson
decays. The generic formulas for the time-dependent and time-integrated decay
rates of both coherent and incoherent D^0\bar{D}^0 events are derived, and
their approximate expressions up to the second order of the mixing parameters
x_D and y_D are presented. Explicitly we discuss D^0-\bar{D}^0 mixing and
various CP-violating signals in neutral D decays to the semileptonic final
states, the hadronic CP eigenstates, the hadronic non-CP eigenstates and the
CP-forbidden states. A few non-trivial approaches to the separate determination
of x_D and y_D and to the demonstration of direct and indirect CP asymmetries
in the charm sector are suggested.
