Download or read book Observation of the Baryonic B Decay B0bar to Lambda_c^+ Anti-Lambda K- written by and published by . This book was released on 2011 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors report the observation of the baryonic B decay {bar B}° 2![Lambda]{sub c} {bar [Lambda]}K− with a significance larger than 7 standard deviations based on 471 x 106 B{bar B} pairs collected with the BABAR detector at the PEP-II storage ring at SLAC. They measure the branching fraction for the decay {bar B}° 2![Lambda]{sub c}+ {bar [Lambda]}K− to be (3.8 ± 0.8{sub stat} ± 0.2{sub sys} ± 1.0 {sub {Lambda}{sub c}+}) x 10−5. The uncertainties are statistical, systematic, and due to the uncertainty in the {Lambda}{sub c}+ branching fraction. They find that the {Lambda}{sub c}+ K− invariant mass distribution shows an enhancement above 3.5 GeV/c2.
