The Time Dependence of B0->f Decays
  We calculate the time dependence of B0->f decays (and analogously D0->f decays) and use this result to obtain expressions for the time dependence of: an untagged sample (B0->f and Bbar->f decays combined), a sample containing charge-conjugate final states (B0->f and B0->fbar decays combined), and a sample containing all four decay modes together. For simplicity we assume CP violating effects are negligible.
