Abstract

Invariant mass distributions of B+ and B0+ combinations are investigated in order to study excited B mesons. The analysis is based on a data sample corresponding to 3.0 fb1 of pp collision data, recorded by the LHCb detector at centre-of-mass energies of 7 and 8 TeV. Precise measurements of the masses and widths of the B1(5721)0,+ and B2(5747)0,+ states are reported. Clear enhancements, particularly prominent at high pion transverse momentum, are seen over background in the mass range 5850-6000 MeV in both B+ and B0+ combinations. The structures are consistent with the presence of four excited B mesons, labelled BJ(5840)0,+ and BJ(5960)0,+, whose masses and widths are obtained under different hypotheses for their quantum numbers.
