Time-dependentCP-violation effects inB0-B¯0systems

Abstract

Large time-dependent partial-rate asymmetries associated with CP violation are predicted for the decays of $B_s$ (≡b¯s) and $B_d$ (≡b¯d) to certain two-body final states (such as $D^{+}$ ${\pi }^{\mathrm{-}}$). Tagging on an accompanying charged b-flavored particle ($B_u^{\mathrm{-}}$=bū) or identified baryon (${\Lambda }_b$≡bud) permits the identification of the initial flavor (B or B¯) of the decaying particle. The asymmetries are contrasted with the $B_d$→ψ$K_S$ asymmetry discussed earlier in the literature.
