Interpretation of Scalar and axial mesons in LHCb from an historical perspective

Abstract

LHCb measurements of $B_{d,s}\to J/\psi +X$ are shown to be consistent with historical data on scalar and axial mesons below 2 GeV. This is in contrast to some recent interpretations of these data. Further tests of our hypotheses in other $B_{u,d,s}\to J/\psi +X$ decay modes are suggested.
