Precision measurement of the ratio of the Λ b 0 to B ¯ 0 lifetimes
The LHCb measurement of the lifetime ratio of the Λb0 baryon to the B-0 meson is updated using data corresponding to an integrated luminosity of 3.0 fb-1 collected using 7 and 8 TeV centre-of-mass energy pp collisions at the LHC. The decay modes used are Λb0→J/ψpK- and B-0→J/ψπ+K-, where the π +K -...
