Indirect search of exotic mesons: B -> J/psi + Anything

High Energy Physics - Phenomenology 2022-03-02 v1

Abstract

We reconsider the discrepancy between theory and data in the momentum distribution of slow J/psi in B decays. Beside an update of the standard color singlet and color octet QCD components, we include the contribution from XY Z exotic mesons, and show that the residual discrepancy could be accommodated considering new XYZ mesons still unobserved.
