The authors' main claim The upper limits on the decay branching fractions are determined to be $\mathcal{B}(\etacpto\rho^{0}\rho^{0})<3.1\times10^{-3}$, $\mathcal{B}(\etacpto K^{*0}\bar{K}^{*0})<5.4 \times10^{-3}$, and $\mathcal{B}(\etacpto\phi\phi)<2.0\times10^{-3}$ at the 90% confidence level.
The compiled record
The paper's own sentences, arranged. Each label is drawn from a closed vocabulary; the number beside it is the probability the classifier gave that label. Numbers in the tables are the authors', checked by code. No sentence in this record was written by a model.

The abstract, sentence by sentence
The processes $\etacpto \rho^{0}\rho^{0}$, $K^{*0}\bar{K}^{*0}$, and $\phi\phi$ are searched for using a sample of $1.06 \times 10^8$ $\psip$ events collected with the BESIII detector at the BEPCII collider. No signals are observed in any of the three final states. The upper limits on the decay branching fractions are determined to be $\mathcal{B}(\etacpto\rho^{0}\rho^{0})<3.1\times10^{-3}$, $\mathcal{B}(\etacpto K^{*0}\bar{K}^{*0})<5.4 \times10^{-3}$, and $\mathcal{B}(\etacpto\phi\phi)<2.0\times10^{-3}$ at the 90% confidence level. The upper limits are lower than the existing theoretical predictions.

No signals are observed in any of the three final states. The upper limits on the decay branching fractions are determined to be $\mathcal{B}(\etacpto\rho^{0}\rho^{0})<3.1\times10^{-3}$, $\mathcal{B}(\etacpto K^{*0}\bar{K}^{*0})<5.4 \times10^{-3}$, and $\mathcal{B}(\etacpto\phi\phi)<2.0\times10^{-3}$ at the 90% confidence level.

With the recent availability of experimental data from BES-III [ref] , we can fit five channels of $η_c→VV$, i.e. $ωω$, $ϕϕ$, $K^*K̅^*$, $ρρ$ and $ωϕ$, to constrain both the short and long-distance contributions.
