Analysis of the mass and width of the $Y(4274)$ as axialvector molecule-like state

Abstract

In this article, we assign the $Y(4274)$ to be the color octet-octet type axialvector molecule-like state with $J^{PC}=1^{++}$ tentatively, and construct the color octet-octet type axialvector current to study its mass and width with the QCD sum rules in details. The predicted mass favors assigning the $Y(4274)$ to be the color octet-octet type molecule-like state, but the predicted width disfavors assigning the $Y(4274)$ to be the color octet-octet type molecule-like state strongly. The $Y(4274)$ may be the conventional charmonium state ${\chi }_{c1}(3P)$, and it is important to observe the decay $Y(4274)\to J/\psi \omega$ to diagnose the nature of the $Y(4274)$.
