Exclusive B Decays into Final States with Two Charmed Baryons
- Univ. of Iowa, Iowa City, IA (United States)
This Thesis presents measurements of the decays B- → Ξ0c$$\bar{Λ}$$-c, $$\bar{B0}$$ → Ξ+c$$\bar{Λ}$$-c, B- → Λ+c$$\bar{Λ}$$-cK-, and $$\bar{B0}$$ → Λ+c$$\bar{Λ}$$-c-K0s based on 228 million (4S) → B$$\bar{B}$$ decays collected with the BABAR detector at the SLAC PEP-II asymmetric-energy B factory. The branching fraction of B- → Λ+c$$\bar{Λ}$$-cK- is measured to be (1.22 ± 0.16 ± 0.14 ± 0.63) x 10-3, and the branching fraction of B0→Λ+c$$\bar{Λ}$$c-$$\bar{K0}$$ is (0.40 ± 0.33 ± 0.05 ± 0.21) x 10-3. The product B(B- → Ξ0c$$\bar{Λ}$$-c) x B( Ξ0c→ Ξ-π+) is measured to be (2.04± 0.59 ± 0.26 ± 0.53) x 10-5, and B($$\bar{B0}$$→ Ξ+c$$\bar{Λ}$$-c) x B (Ξ+c → Ξ-π+π+) is (1.50 ± 1.07 ± 0.19 ± 0.39) x 10-5, where the uncertainties are statistical, systematic, and the uncertainty from the branching fraction B(Λ+c → p+ K-π+), respectively.
