摘要：

Very recently, the CMS Collaboration reported a peaking phenomenon existing in the di-J/psi invariant mass spectrum from pp collision, by which the X(6900) structure announced by the LHCb Collaboration was confirmed, but also more enhancement structures were discovered. Facing such a novel phenomenon, in this work we indicate that these new features reflected from the CMS measurement provide a good implication for a dynamical mechanism which reproduces the novel peaking phenomenon in the reported J/psi-pair mass spectrum well. This mechanism is due to special reactions, where different charmonium pairs directly produced by pp collision may transit into the final state of J/psi J/psi. The present work provides a special viewpoint to decode these observed fully charm structures in the J/psi-pair invariant mass spectrum.
