Novel charmonium-like structures in the $J/\psi \varphi$ and $J/\psi \omega$ invariant mass spectra

Abstract

Stimulated by the new evidence of Y(4274) observed in the $J/\psi \varphi$ invariant mass spectrum, we first propose the charmonium-like state Y(4274) as the S-wave $D_s{\bar{D}}_{s0}(2317)+h.c.$ molecular state with $J^P=0^{-}$, which is supported well by dynamics study of the system composed of the pseudoscalar and scalar charmed mesons. The S-wave $D{\bar{D}}_0(2400)+h.c.$ molecular charmonium appears as the molecular partner of Y(4274), which is in accord with the enhancement structure appearing at 4.2 GeV in the $J/\psi \omega$ invariant mass spectrum from B decays. Our study shows that the enhancement structures, $i.e.$, the newly observed Y(4274) and the previously announced $Y(4140)/Y(3930)$ in the $J/\psi \varphi$ and $J/\psi \omega$ invariant mass spectra, can be understood well under the uniform framework of the molecular charmonium, which can be tested by future experiments.
