论文摘要
在本调查中，我们评估退出状态的中等内部衰减宽度$ψ$（4040）和$ y $（4008）衰减，以对非爆炸的伪内科$ d \ bar {d} $ d_s $ d_s $ d_s \ bar d_s $ d} $ d} \ bar {d}^*$ meson和pseudoscalar-vector $ d \ bar {d}^*$ mesons使用$^3p_0 $模型。中等效应通过女儿介子的中等内质量（使用手性SU（3）模型和QCD总规则方法计算在我们以前的工作中）。我们将$ψ$（4040）和$ y $（4008）状态视为3 $^3S_1 $状态，并在给定的衰减模式下观察一个州的中等统治地位。本调查的结果将证明是向有争议的$ y $（4008）状态分配正确的光谱状态的一步。
In the present investigation, we evaluate the in-medium partial decay widths of exited states $ψ$(4040) and $Y$(4008) decaying to the pairs of non-strange pseudoscalar $D \bar{D}$ mesons, strange pseudoscalar $D_s \bar{D}_s$ mesons, non-strange vector $D^* \bar{D}^*$ meson and pseudoscalar-vector $D \bar{D}^*$ mesons using $^3P_0$ model. The in-medium effects are incorporated through the in-medium masses of daughter mesons (calculated using the chiral SU(3) model and QCD sum rule approach in our previous works). We consider $ψ$(4040) and $Y$(4008) states as 3$^3S_1$ states and observe the in-medium dominance of one state over the other for a given decay mode. The results of the present investigation will prove as one step forward in assigning the correct spectroscopic state to controversial $Y$(4008) state.
