Identification of Neutral B Mesons Using Correlated Hadrons

Abstract

The identification of the flavor of a neutral $B$ meson can make use of hadrons produced nearby in phase space. Examples include the decay of ``$B^{\ast \ast }$'' resonances or the production of hadrons as a result of the fragmentation process. Some aspects of this method are discussed, including time-dependent effects in neutral $B$ decays to flavor states, to eigenstates of CP and to other states, and the effects of possible coherence between $B^0$ and ${\overline{B}}^0$ in the initial state. We study the behavior of the leading hadrons in $b$-quark jets and the expected properties of $B^{\ast \ast }$ resonances. These are extrapolated from the corresponding $D^{\ast \ast }$ resonances, of whose properties we suggest further studies.
