Measurements of b-hadron masses are performed with the exclusive decay modes B+→
J/ψK+, B0→ J/ψK⁎ 0, B0→ J/ψKS0, Bs0→ J/ψϕ and Λb0→ J/ψΛ using an integrated
luminosity of 35 pb− 1 collected in pp collisions at a centre-of-mass energy of 7 TeV by the
LHCb experiment. The momentum scale is calibrated with J/ψ→ μ+ μ− decays and verified
to be known to a relative precision of 2× 10− 4 using other two-body decays. The results are
more precise than previous measurements, particularly in the case of the Bs0 and Λb0 …
