论文摘要
在物理中。 Rev. {\ bf D103}（2021）074015（ARXIV：2101.07281），获得地基状态之间的巨大（或最大）质量差距，以及第一个径向激发态的tetraquark分子状态，获得$δ= 1.70 = 1.70 \ sim 2.35 \，\ sim 2.35 \，\ rm rm rm c}我们详细介绍了操作员产品扩展，Borel Windows等中的问题。
In Phys. Rev. {\bf D103} (2021) 074015 (arXiv:2101.07281), huge (or largest) mass gaps between the ground states and first radial excited states for the tetraquark molecular states are obtained, $Δ=1.70\sim 2.35\,\rm{GeV}$. We explore the problems in the operator product expansion, Borel windows, etc, in details.
