The high accuracy $\phi $-meson photoproduction data from the CLAS experimentin Hall~B of Jefferson Laboratory allow us to determine the near-thresholdtotal cross section of the $\gamma p\to\phi p$ reaction and use it forevaluating the $\phi p$ scattering length $\alpha_{\phi p}$. These data resultin an absolute value of $|\alpha_{\phi p}| = (0.063\pm 0.010)$~fm, which issmaller than the typical hadron size. A comparative analysis of $\alpha_{\phip}$ with the previously determined scattering lengths for $\omega p$ and$J/\psi p$ from the A2 and GlueX experiments is performed.

Comparative analysis of $\omega p$, $\phi p$, and $J/\psi p$ scattering lengths from A2, CLAS, and GlueX threshold measurements
