Measurements of b-hadron masses are performed with the exclusive decay modes B+ -> J/Psi K+ ,B0 -> J/Psi K∗0 , B0 → J/Psi K_S , B_0 -> J/Psi Phi and Λb → J/Psi Λ 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.

Abstract

Measurements of b-hadron masses are performed with the exclusive decay modes B+ -> J/Psi K+ ,B0 -> J/Psi K∗0 , B0 → J/Psi K_S , B_0 -> J/Psi Phi and Λb → J/Psi Λ 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/Psi -> mu+ mu- decays and verified to be known to a relative precision of 2 x10^-4 using other two-body decays. The results are more precise than previous measurements, particularly in the case of the B0s and Λb masses.
