Event Selection and Background Suppression Principles
- candidates are reconstructed in the CsI calorimeter barrel region
- candidates are identified using time-of-flight and dE/dx info
- Displaced vertices are used to identify candidates
- Scaled Momentum criterion: xp > 0.5 or 0.6, where xp ? p/pmax and
- reduces combinatorial background
- Note: charmed baryons with B-meson parents have xp < 0.4
