Invariant mass distributions of B+pi- and B0pi+ combinations are investigated in order to study excited B mesons. The analysis is based on a data sample corresponding to 3.0 fb-1 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 B_1(5721)^(0,+) and B_2*(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+pi- and B0pi+ combinations. The structures are consistent with the presence of four excited B mesons, labelled B_J(5840)^(0,+) and B_J(5960)^(0,+), whose masses and widths are obtained under different hypotheses for their quantum numbers.

Elastic Form Factors of Axial-Vector Mesons: A Contact Interaction Exploration
hep-ph 2026-05 unverdicted novelty 5.0
A contact interaction model in the Dyson-Schwinger/Bethe-Salpeter framework produces elastic form factors for axial-vector mesons, with the electric form factor crossing zero at lower momentum than for vector mesons a...
