  "abstract": "Very recently a new enhancement around 4.05 GeV was observed by Belle experiment. In this short note, we discuss some possible assignments for this enhancement, i.e. $\\psi(3S)$ and $D^*\\bar{D}^*$ molecular state. In these two assignments, Y(4008) can decay into $J/\\psi\\pi^0\\pi^0$ with comparable branching ratio with that of $Y(4008)\\to J/\\psi\\pi^+\\pi^-$. Thus one suggests high energy experimentalists to look for Y(4008) in $J/\\psi\\pi^0\\pi^0$ channel. Furthermore one proposes further experiments to search missing channel $D\\bar{D}$, $D\\bar{D}^*+h.c.$ and especially $\\chi_{cJ}\\pi^+\\pi^-\\pi^0$ and $\\eta_c\\pi^+\\pi^-\\pi^0$, which will be helpful to distinguish $\\psi(3S)$ and $D^*\\bar{D}^*$ molecular state assignments for this new enhancement.",
