| contents | Under the framework of the vector meson dominance model (VMD), the absolute scattering lengths of light vector mesons ($ϕ$, $ω$, and $ρ$) with the deuteron are calculated from the cross sections of vector meson photoproduction off a deuteron. Additionally, a fitting function is used to predict the scattering lengths of the heavy vector mesons $J/ψ$-$d$ and $% Υ$-$d$. Based on these results, the distribution of the scattering lengths $|α_{V d}|$ between vector mesons and the deuteron is presented for the first time and compared with the scattering lengths $|α_{V p}|$ between vector mesons and the proton. It is found that as the mass of the vector meson increases, the scattering lengths $|α_{V d}|$ become closer to $|α_{V p}|$. In addition, the correlation analysis indicates a strong positive relationship between the scattering length and the vector meson radius, with a high correlation coefficient. The implications of results are essential for improving our understanding of the interaction between hadron and nucleus. |
