Abstract: We report an analysis of the Λb0→Λc+π -π +π - decay in a data sample collected by the CDF II detector at the Fermilab Tevatron corresponding to 2.4fb -1 of integrated luminosity. We reconstruct the currently largest samples of the decay modes Λb0→Λ c(2595) +π - (with Λ c(2595) +→Λc+π +π -), Λb0→Λ c(2625) +π - (with Λ c(2625) +→Λc+π +π -), Λb0→Σ c(2455) ++π -π - (with Σ c(2455) ++→Λc+π +), and Λb0→Σ c(2455)0π +π - (with Σ c(2455)0→Λc+π -) and measure the branching fractions relative to the Λb0→Λc+π - branching fraction. We measure the ratio B(Λb0→Λc+π -π +π -)/B(Λb0→Λc+π -)=3.04±0.33(stat)-0.55+0.70(syst) which is used to derive B(Λb0→Λc+π -π +π -)= (26.8-11.2+11.9)×10 -3. © 2012 American Physical Society.
