Abstract

With an integrated luminosity of 2.47 fb -1 recorded by the ATLAS experiment at the LHC, the exclusive decays B $$0atop{s}$$→ J / ψ Φ and B $$0atop{d}$$ → J / ψ K * 0 of B mesons produced in p p collisions at √ s = 7 TeV are used to determine the ratio of fragmentation fractions f s / f d .
