Measurement of the branching fraction B(Λ[subscript b][superscript 0]→Λ[subscript c][superscript +]π[superscript -]π[superscript +]π[superscript -]) at CDF
We report an analysis of the Λ[subscript b][superscript 0]→Λ[subscript c][superscript +]π[superscript -]π[superscript +]π[superscript -] decay in a data sample collected by the CDF II detector at the Fermilab Tevatron corresponding to 2.4 fb[superscript -1] of integrated luminosity. We reconstruct...
